    I bought a full set or rear LED’s from Doug.
    Delighted with the quality of all the products, and the installation videos.
    I found it easier to install the Rear Light Clusters by lifting the boot floor.
    The support from Doug during the installation was first class and never ending.
    I cannot recommend his products or him highly enough.

    Impressive product quality and very straightforward to fit as it plugs into the existing econoseal connectors. I thought that maybe the self-tappers would be too short (the LED plate and washers take up a bit of extra space) but it all tightened up ok. Huge difference in illumination (see photos for tail and stop lights). An excellent upgrade.

    Thanks Doug, These units are obviously made to a very high standard and fit very easily. The relay corrects the otherwise over fast flasher. I did find that with the added thickness of the washers and the printed circuit board some screws (upper) were too short to secure the light unit to the wing. Great product, thank you.

    Fitted the rear light clusters Saturday afternoon took about 30/40 mins .Very pleased ,work perfectly nice and bright easy to fit.
    As I drive my Seven a lot throughout the winter and in all weathers through the summer I felt I needed to upgrade my lights and will be replacing the rest of the rear lights soon ( well probably this wednesday actually as I already ordered the fog and number plate led replacements!) Thank you for the quick delivery as well!

  12. Simon Salter (verified owner)

    Fantastic product and excellent customer service, it’s so nice to deal with a small company that really takes care of there customers. These lights are the best upgrade I’ve made to my car, no longer need to worry every time I brake that the car behind has seen my brake lights.

    These are like strapping photo cannons on the back of the 7! Next to the asthmatic fireflies in the stock lamps these beasts are bright and punchy even in daylight. After fitting these got loads of positive comments from other 7 owners and most importantly I feel other road users respond better to my signalling.

  15. Ned Kershaw (verified owner)

    I originally bought the rear set up as they are so much better than standard and I would do anything to let people know I am there…visually great. I would like to see the impending high level light to go with the set up. I have also added the front main indicators based on the original quality and brightness of the rear. Big thumbs up .

    I would consider this the best money spent on an upgrade. I would not be without it. I have a picture of the difference that the tail lights make for comparison. Without a doubt your product displayed on the left provides me a better sense of comfort knowing I will be seen from the rear. Thank you Just add Lightness you have some great products that really make a difference!

    Having just bought my first caterham I was directed to JAL for a light upgrade as a first upgrade. I wasn’t disappointed! The JAL lights were so easy to fit even for a ham fisted buffoon like me! The difference between the standard lights and the JALs is night and day (pardon the pun). Bright, clear and look the part. I can not recommend these as your first (or any) upgrade. Well worth every penny.

    I decided to change my rear lights after I followed a friend of mine that has the same R300 : I could just not see when he was braking and decided for safety reasons to make the invest. What can I say? Friendly service, rapidly delivered from the UK to France, well packed. The lights were easy to put, even if I asked my mechanic to do it during the winter maintenance. I just did not anticipate je would have to change the flasher relay to make it work properly. I am fully satisfied with the result: I can see a major change in the lights when brakes are activated. I will add pictures to show with no lights on, rear lights and brakes lights to show that despite the very sunny day, we can see a difference. Thanks JAL !

    Excellent product and customer service, the flasher relay we ordered didn’t work for our 7 but a new one was sent out free of charge and worked like a dream.
    Our lights are so much brighter now – I feel a lot safer been people are following!

    Great product and simple to fit. Even included new relay which was needed.

  41. Garry Talbot

    If you are a 7 owner then this is probably the most important safety upgrade you will ever undertake and also one of the easiest. It took me 30 mins and I don’t consider myself in anyway accomplished at this sort of things.

    Initially you might think these are expensive but when you consider the added safety provided by these lights they are a great investment.

  42. Michael Walsh

    Rating for LED lights? Give them a 5+

    I recently purchased a pair of rear light clusters for my 7. All I can say is that the result is "Brilliant" in every sense of the word. I almost feel sorry for anyone driving behind me, but at least "I didn’t see you" is unlikely to be heard.

    If only dealing with other companies were as pleasant.

    PS You seem to be the only LED supplier that has realized that the average customer can’t use a soldering iron, hasn’t got a crimp tool, can’t understand the wiring diagram (which doesn’t correspond to the model of car that he owns) and would rather spend his free time driving the car anyway.

    Keep up the good work.

  43. Eric Downer

    Very easy and straight forward to fit. These units provide a major improvement to the rear light performance, are very well engineered and look brilliant – (couldn’t resist the pun).

  44. Mark Watkinson

    What a difference these lights make. So, so pleased with them. And I feel so much safer when out in the car. Thanks for developing these, I no longer hold my breath wondering if the numpty behind had seen my brake lights. Amazing product.

  45. Neal Evans

    Quality product which is a direct replacement for the original units. Built using the same base and lenses but the traditional bulbs have been replaced by a high quality LED board meaning fitting is straightforward and instructions are supplied if needed. There is a strong likelihood you will need a new flasher relay for the indicators to flash at the correct speed but this can be ordered with the units. 15 minutes should be the average fitting time and you shall benefit from being seen by the motorists behind you!

  46. Low Flying

    The difference really is chalk and cheese, the LED lights are just so much brighter…when you touch the brake pedal the difference is immediate and highly visible.

  47. Yahoo Motoring

    After coming down and installing the new versions, the difference was immediately noticeable – especially now the nights are starting to draw in.

  48. Garry Hooton

    Everything exactly as advertised – easy to fit, lovely and bright – small experiment with relays (handled promptly and professionally by Doug – next day solution!) to sort the indicator speed, very pleased with this "safety upgrade".

  49. Wenceslao Garcia

    The LED lights come in a very easy to install kit with great quality and the brightness is superb so it is a great option to add safety to our little cars. Good service.

  50. Jack Bayliss

    Brilliant and so much clearer for others to see. Great on track.

  51. Geoff Martin

    Excellent. Very bright & easy to fit.

  52. David Hemmings

    A massive improvement over the standard units and very straightforward to change over. Just Add Lightness were good to deal with – very communicative and my order was delivered very quickly.

  53. James Lark

    I ordered this product as I felt the existing lights just weren’t bright enough. I managed to fit them just before a rain drenched weekend in France and was I glad I fitted them as It gave me greater confidence that I would be seen. Very quick response to the pedal and fantastic brightness. Fitting was easy but I had to use bolts for the top mounting holes as the existing screws were not long enough to get a good fix. However, swapped the top screws with the bottom ones and some M5 bolts in the top and all sorted. Overall, took no longer than 45 minutes to do both sides including the relay change. Really pleased with the product and will be looking to upgrade other bits in due course. Thoroughly recommended.

  54. Steve Nelson (verified owner)

    Great service-received the package 6 days after I ordered it from the UK to the US. Taillights are bright and easy to install! Just to repeat what a couple other reviews said-it is easier if you remove the rear wheels so you can reach around inside while installing the lights. Then you can get your hand next to the fuel tank and push the connector and the grommet out. Also make sure you have a relay flasher that is made for LEDs so you are clicking at the right speed. It is a joy to know I won’t have to replace bulbs again and drivers behind WILL see me.

  55. George Ince

    Fantastic product and very easy to fit! Managed to do so on a lunch break at work without breaking a sweat! Especially needed when it’s my only car with the weather getting darker.

  56. Phill Greetham

    It’s a direct replacement and much brighter, what’s not to like

  57. Mike Askew

    Excellent piece of kit and Doug was very helpful and responsive in answering queries, even over a Bank Holiday weekend. Huge improvement over the standard fitting.

  58. Clairbois Jimmy

    Easy installation, works perfectly 🙂
    I recommend it !

  59. Carl Flemister

    Excellent lights! Huge increase in brightness over stock and an easy fit/install in stock location.

  60. Neil Mckillup

    The self tapping bolts provided to secure the unit to the wing could do with being just a little bit longer. I have had to fit my units without the washers on the front face to make sure I have a good hold in the wing.

  61. Stephen Gradon

    Excellent light produced from the replacement cluster. Plug and play, although the spacing block required several attempts to get it to sit flush with the rear wing. Maybe it was me

  62. Michael Faulkner

    Fantastic lights! Other cars can now see my brake lights clearly during the day

  63. John Cannon (verified owner)

    I had tried LED replacement lamps and was initially pleased with the improvements but I found after a while the lamps were sagging in the lamp holder and were missing the reflector probably due to the Caterham’s firm ride and the weight/length of the LED lamp. This is what led me to change to JAL LED’s, I was very impressed with the quality you can see they are made very well, You get a block of light rather than just the middle of the lens . I feel a lot happier now maximising the availability of lens and retaining the Seven look. I also changed the Fog and the Reversing light hopefully with less load the battery will last longer !

  64. Nick Wakefield

    Easy to fit and a marked improvement on the originals

  65. John Cockburn

    The LED rear light cluster is a must for every Cateham owner, they are very bright, a direct replacement and easy to fit. My only concern is the original fixing screws seem too short so I have replaced them with stainless nuts/bolts making sure not to over tighten them. Great product

  66. Paul Lyrick

    I have to date replaced my Severn’s rear light clusters, front indicators and fog lamp with the LED solutions from Just Add Lightness. I am absolutely delighted not just with the vast improvement in luminosity but the fabulous customer service I have received along the way. I would highly recommend these lights as well as engaging with this company for a great service to boot!

  67. Jeremy Brown

    Nicely designed and built LED panels. Installation is easy although be aware that you need longer length screws and as I had fitted stainless ones, some of mine were too short and needed replacing.

    Once fitted, they do look good and work well with a more even and crisper light.

  68. Rob Oldland

    Hi Doug,

    I hope you don’t tire of hearing praise for your products and service? Because here’s another!

    I have fitted my LED rear lights and new relay, worth every penny. My last Caterham was written off (as featured recently in LowFlying) when a car hit me from behind in light mist conditions. I just wonder if this product would have saved my last car?!

    Anyway, I look forward to continuing the LED upgrades during the year.

    Thanks again and best wishes for 2018.

  69. Len Elkington

    Good quality units and relatively easy to fit; to fit the n/s one I had to remove the boot floor (no big deal) as Caterham hadn’t left any slack in the wiring loam for me to remove the plug via the wheel arch. The o/s one needed a little bit of manipulation to get all the screws in as the curvature didn’t quite match that of the wheel arch. Again no big deal.

  70. Tim Carter

    I had a few "issues" but support (Doug) was wonderful at dealing with, what turned out to be, my incompetence! I fitted light clusters to the rear and new flasher lights to the front of my 7 and now feel more confident about my visibility. Of course, only time will tell! Given my experience, I would recommend you order with the confidence on good customer support. Tim

  71. Thomas Meacham

    Package arrived in Alaska USA safely. I have not yet installed the lights.

  72. John Wilson

    A top quality product. One of the two units required only minor trimming of a small excess of rubber from the moulding process. The holes matched up perfectly with the existing holes in the rear wings. Some owners may find access to the wiring connector easier after removing the rear wheel. The lights are much brighter than the original outdated filament type and will add greatly to visibility of the car from behind. This is bound to be a very popular replacement for Caterham 7 owners. Well done Doug.

  73. Paul Bennett

    Significant enhancement to rear illumination which is an essential on a Caterham 7. Delay in manufacture of components meant a slightly prolonged delivery schedule but worth the wait as this appears to be a quality product.

    Only issue was with getting to the connector behind the wheel arch on the offside which proved a little tricky but that’s nothing to do with the product and more about the ‘joy’ of owning a Caterham.

  74. Stephen Long

    Really excited about these lights. They look fabulous and will give me a feeling of security when travelling at night and in poor light conditions. Also brings the car up to date.

  75. David Greening

    The lights were of excellent quality and were very easy to fit.Significantly brighter than the original units.

  76. Richard Frost

    Just got round to fitting these. Great result. Did one side at a time to check the difference, stunning.

  77. Alastair Westle

    The quality of the rear light clusters is very good indeed. The only criticism it that the side light brightness is a little too bright meaning not much difference when brakes applied.

    I don’t feel that the price reflects good value for money at all. The justification for my opinion is that the product includes the rubber mounts and lenses that every car owner already has. In this day and age we should be recycling not creating unnecessary waste.

  78. Garry Talbot

    A superb safety feature, easy to fit and a night and day change to the light output.


    What an incredible transformation !!! The new LED lights are so much brighter and clearer. No longer will I have to look back in my mirrors and worry of the car behind has seen me stopping or not !!
    Totally recommend them 100%

  80. Patrick Zahner

    this light run perfect and these are amazing

  81. Simon Smith

    Fantastic product! Fitting was a doddle & the difference is truly amazing,it has to be seen to be believed!
    The only slight critics is is that the outer cable sheathing could be a bit longer to cover all if the wires,apart from that very happy,thanks again.

  82. Andre Daners

    Very bright LED and really good quality. I’m very happy with my new rear lights

  83. Chris Hardman

    After surviving about 40 Italian road tunnels en route to Portofino and the madmen within I can only say they work well!
