This guide shows you how to bypass the built-in Piaggio indicator relay and fit a universal 2-pin indicator relay instead. 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. By adding resistors to the wiring you increase the wattage draw from the LED indicators to match what was there before, therefore your existing relay will continue to run as normal with a standard flash rate. The voltage regulator/ flasher relay can be located in different places depending on which moped you have. On the Gilera Stalker used for this blog it is located behind the front fairing panel (behind the headlight). On a Piaggio Zip it is located behind the left hand rear panel (on the side of the seat).

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. These electronic relays will keep your flash rate constant and keep it standard even if the load on the circuit changes. Standard relays will not flash at the correct rate with LED bulbs. Once you know you have the relay it's as simple as wiring your new motorcycle indicators in and plugging in your new relay!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? As the difference in wattage between LED and standard indicators is generally quite large, it is recommended that you will need one resistors per indicator that you are changing. You can buy 25 watt resistors in pairs here. 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. Most Piaggio/ Gilera mopeds are fitted with an indicator relay which is built into the voltage regulator unit. a) install resistors (extra solder joints, bulky, generate heat, waste power, weigh a little bit, look fugly)

This applies to EU and other bikes with hazards and 4 pin relays, type Mitsuba FR33-025 (however, if you show me the insides of a 2 pin I can advise as well)You might have been put off making the change in the past because of all the talk about calculating wattage of bulbs and determining which units to buy, however it's not as difficult as it sounds. Fitting new LED indicators is an easy task for anyone with simple electrical knowledge. Test your indicators for each resistor you fit to ensure that they are working correctly and to determine if any more are needed to further slow down the flash rate.
12V ELECTRONIC INDICATOR FLASHER / HAZARD RELAY CLASSIC CAR
Maybe you only want to change your rear indicators to LEDs and leave the front indicators standard, or you're struggling to find the right LED relay for your bike. If that's the case then you will need to fit resistors in your wiring circuit. Fits all the Bonneville range carburettor models, Thruxton, T100, America, Speedmaster and Scrambler. Also fits EFI Bonneville range up to VIN 521668. Related productsResistors get hot during operation, so wrapping them in tape can lead to resistor over heating or worse melting plastic parts around it. So, to slow your flashing down you have to make the wattage draw similar to how it was with the original indicators, and you can do this by fitting either a new indicator relay unit or with resistors. 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. 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? Resistors need to be fitted in parallel to the indicator, meaning one end connecting to the positive and one end connecting to the negative.

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. We need to extend this wire and fix a spade connector onto the end. Similarly we need to splice into one of the red/white wires and connect in another wire with another spade connector as in the picture below... Suitable replacement for 3 pin flasher relays with 49 (X), 49a (L) and P Connectors. You will need to also connect the earth connection wire. Also available with Positive Earth, please select the required option from the drop down menu. One of the problems with this is you have to get the resistor value just right. If you fit just rear LED lights and get them flashing correctly you may need to change the resistors for different value ones if you then late additionally upgrade the front indicators.
Getting the right LED relay for your motorcycle in most cases just means pulling out your existing relay and buying an LED specific relay that matches the pin lay-out of your current relay. More importantly this conversion also enables you to fit an LED indicator relay as the indicator relay built into the Piaggio voltage regulator will not flash properly with LED indicators fitted.
