Brand: JAL


Our Caterham 7 Rear Light Cluster LED Upgrade Kit replaces the original incandescent bulbs inside the rear light cluster with a modern JAL LED panel.

Each replacement LED panel consists of 72 ultra bright, wide angle LED’s. 36 on each side for stop/tail and indicator functions. The LED panel is a high quality bespoke design for any car using this rear light cluster.

All wires and connectors are supplied and with a simple modification to the cluster inner plate you can retain the classic Caterham 7 look, with an E marked lens but with high performance OSRAM LED lights inside.

PLEASE NOTE: JAL is the market leader in Caterham LED upgrades. We have seen many fake LED upgrades come and go. They may look the same but, they consist of different components and they are generally cheap Chinese copies, with no guarantee of reliability or quality.

Our LED upgrades are designed by us and manufactured to ISO Standards in the UK. We hold the design rights for our products and you will not find a higher quality LED upgrade for your Caterham.

LED Safety

LED brake lights are proven to reduce the reaction time of a driver in a following vehicle and considerably reduce their stopping distance.

A difference in reaction time of just 0.2 seconds at 75 mph translates into 21 feet extra braking distance for the cars behind. This can literally be the difference between life and death.

This is an easy upgrade and is one of the best safety modifications for your Caterham 7.

Please note the following:

  1. Please read the installation instructions before purchase.
  2. You will need to upgrade your flasher relay to an LED type (see our LED relay below).
  3. The LED’s are coloured red/amber and will work perfectly with both the standard and clear lens.

  6. Guy (verified owner)

    Brilliant upgrade to any Caterham. It’s difficult to show in the pictures just how much brighter the LED lights are compared to normal. Also an ideal opportunity to change over to clear indicators to bring the car up to date. Really easy to install – just follow the video on the JAL Youtube channel. Great service and support – thanks Doug.

    Excellent product, the lights are a significant improvement on the originals and using the video on the website makes fitting them a doddle, I would definitely recommend these to anyone

    These are better than I could have expected, and super easy to install. The instructional videos were also a great help though. I can’t fault them, I’ll be back for the rest of the lights soon!

    Relatively easy to fit. Had a query regarding undoing the econoseal connector which was quickly answered. With all things Caterham always something crops up that is unexpected. In my case the new econoseal connector wouldn’t fit through the hole in the rear mudguard. Rather that butcher the new connector I used the old one. Lights work well.

    I was a bit skeptical at first, especially because here in Southern California the sun is present almost all year long, but boy was I wrong! This is a must have on a Seven! These LEDs are absolutely brilliant! Super bright no matter how clear the sky is and it keeps the original look of the Seven! Highly recommended!

    Doug is very kind and professional, fast delivery. Not mounted yet but seems to be easy. Nice to have a good Led panel for existing rear lights that I prefer to new Caterham rear Led lights (too modern).

  24. Richard S. (verified owner)

    Great conversation kit for anyone with standard rear light clusters and provides much brighter lights. Easy to fit as long as you’re a reasonably practical person – the instruction video is very good.

  30. Jon Dean (verified owner)

    Simply amazing, if you don’t do anything else to your car for safety do this. The upgrade kit is so easy to fit and much brighter that the old filament bulbs I had. Very happy I made the purchase decision and I feel that I now stand more of a chance of being seen.

  33. Michael Margetts (verified owner)

    Much brighter than originals and straightforward to fit, though connectors needed a little trimming to fit through mudguard hole, and drilling out the rivets on backplate not as easy as they make it look!

  34. John B. (verified owner)

    Easy to fit if you watch the video a few times. What a difference, very pleased with the end result

  39. Mark Evans (verified owner)

    gbEngland, United Kingdom

    Very easy to follow instructions by video accessed from the website. I would suggest purchasing new lens screws (I got from the Caterham parts site) and 4x #12 x 1 inch and 4x #12 x1.5 inch pozi pan head self tappers in stainless steel for the light block fixings. The results are great now I have modern car levels of brightness and I paired this with the high level brake lights giving me much more confidence that I will be seen in strong sunlight.

  40. Simon R. (verified owner)

    Simple but very effective, as I want to be seen! Very straight forward to fit, follow VT. It was a bit fiddly for me, but I’m very impatient. Would recommend.

    Hello. I just had clear lense at the rear of my car and with the JustAddLightness kit, I now have colored lights (particularly for the red side), besides being way more brighter than the previous bulb lights setup. A great buy! Thank you.

    The look of your car is still the same. But the light output of your lights is more then double! It is a must have safety advice. When lit it looks also very cool too. As a caterham is a very small car we have to protect ourselves from being not seen. I am a motorbike driver also and in my experience riding with bikes I really realize that everything that can help us to be seen in the trafic can avoid accidents.

    Very quick response to order. It was as easy to install as the JAL video suggested. I had delayed buying the new lights complete because of the waste of the existing units but this upgrade kit was the answer. Only confusion was the differing wiring colours to my existing lights but a quick email to Doug easily solved that.

    Great to see these available as a DIY upgrade! Will be fitting them over Christmas.
    Update with I hope a useful comment about the instructions which say to cut the wire and to use a pair of pliers to remove the reflectors.
    Neither are necessary – you can remove the econoseal pins from the connector with a small screwdriver, enabling the existing plug to be reused/kept as a spare, and the reflectors can be drilled off without damaging them, so the process can be reversed in future.

  58. Lee T. (verified owner)

    Great instructions and videos. Installation is very easy. The rear lights make a huge difference to visibility. I would say that the standard Caterham lights are pretty dangerous, they are so dim compared to modern vehicles. Amazing safety feature. I use my lights all the time to maximise my visibility to other vehicles, being in such a small and low car. My next upgrades will probably be the high level brake light, and possibly headlamps, as driving at night is not great with the standard headlamps.
