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? Most Piaggio/ Gilera mopeds are fitted with an indicator relay which is built into the voltage regulator unit.

Indicator/Flasher Relay 3 pin (Original and LED Indicators)

Suitable for many other classic or modern 12v cars or applications with standard filament / incandescent bulbs or LEDs or a mix of filament / incandescent bulbs and LED.

way they work out how fast to allow flashing is by the wattage of the system. When you fit LED indicators you adjust the wattage of the system and therefore need a new relay to suit (Or fit resistors). a) install resistors (extra solder joints, bulky, generate heat, waste power, weigh a little bit, look fugly)

When it comes to upgrading your current indicators to an LED set, simply plugging in the new units isn't quite enough (although fitting them properly doesn’t require you to be a neuroscientist). The red/white wires connect directly to the +12v positive connection on the battery after passing through the ignition switch and scooter main fuse so is a perfect place to take the power supply for our LED indicator. PLEASE NOTE: We have seen many fake 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. IF THE RELAY DOES NOT BEHAVE WHEN THE ENGINE IS RUNNING YOU NEED TO ADD SUPPRESSION TO THE LEAD BETWEEN YOUR COIL AND DISTRIBUTOR TO REDUCE THE RF INTERFERENCE. Cut into the relay case, very carefully, and don't go deep. From about 1.5cm to 2.5cm from the top of the relay on the printed side, roughly where you should see >PBT+GF30<. Do not cut deep as the circuit board is only 3-4mm away from the plastic casing.This unit is also excellent with most LED indicators. Unlike the original incandescent bulbs, LED lamps are polarity sensitive so you may need to try swapping the connections to each indicator to get the indicators to work okay. We have tested many LED relays on the market and we have found this one 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 our LED flasher relay will work every time at the correct flash speed. This relay has been specifically designed to handle any LED/standard bulb combination. Where other relays fail, this one does not.
