SKU: LED Flasher Unit Relay (CF14) Categories: ,
Brand: Just Add Lightness


This relay and it replaces the standard relay when you upgrade to LED lights. It corrects the indicators flashing too fast without the need to use a load resistors. This relay has been tested on Caterham’s with the Just Add Lightness LED lights.

Why do I need this?

LED lighting draws much less power (load) and lasts way longer than standard incandescent lighting. Replacement of indicator bulbs with LED’s will cause the indicators to flash too fast. This happens because your new LED lights draw such little power. Installing an LED flasher relay specifically designed for LED lights is the easiest method to solve this problem. 

What about load resistors?

Some people choose to fit load resistors to imitate the load of the incandescent (standard) bulbs that they have just removed. This results in more wiring, things may get hot and you are probably using more power than the standard bulb set up that you just replaced! Installing an LED flasher relay is the easiest way to solve the problem.

Whats the difference between this LED fasher unit relay and other LED relays?

We have tested many LED relays on the market and we have found the CF14 to be the best. Some LED relays will work perfectly with either rear LED lights or front LED lights but not both!  No two Caterhams are the same and we have found that after extensive tests (with the help of our customers) that the CF14 LED relay will work every time at the correct flash speed. The CF14 relay has been specifically designed to handle any LED/standard bulb combination. Where other relays fail, this one does not. 

PLEASE NOTE: We have seen many fake CF14 LED relays on the market. They look the same but have different components inside and the casing is made from an inferior plastic. We have even tested some where the positive and negative terminals were incorrectly labelled. Please ensure you have a suitable LED relay fitted to your Caterham when upgrading to any type of LED light.
