How to Rewire Motorcycle Turn Signals?


Rewiring your motorcycle turn signals can be a challenging task. Before you begin, you need to understand the wiring diagram, the colour code for the wires, and the components that make up the turn signals. These components include a Relay, Load balancing resistors, and a Wire Colour Code. Using the diagram and the instructions in this article, you should be able to rewire your motorcycle turn signals.

Wiring diagram

You can find a wiring diagram for motorcycle turn signals on the internet. You can also read this guide. You need to know the connection points of your turn signal bulbs and the wiring for your motorcycle’s turn signals. The wiring of your motorcycle’s turn signals is easy, and this article will show you how to do this on your own. Here are some basic instructions:

Colour code of wires

There are several ways to identify the wires on your motorcycle, but the easiest way is to simply look at the individual turn signal wires themselves. You will be able to determine whether a particular turn signal is on the left or right side based on the color of the wire harness for that particular turn signal. The ground wire, however, will be the same as the rest of your bike’s wiring, so it’s not always possible to tell which side is up or down.


If your turn signal is malfunctioning, you may need to replace the relay for motorcycle turn signals. If you have integrated tail lights or aftermarket signal lights, the original flasher may not work properly. However, a special load-independent LED flasher relay will solve this problem. You can find an inexpensive alternative to a traditional flasher. Alternatively, you can purchase the Kellermann Universal Turn Signal Relay, which is slightly more expensive.

Load balancing resistors

The main purpose of load balancing resistors for motorcycle turn indicators is to prevent them from flashing rapidly. This is because LEDs use a lower amount of electricity than standard incandescent bulbs. These load balancers are used in conjunction with LED lighting to minimize the amount of electricity used for each turn signal. LED lights also use a lower amount of current than stock incandescent bulbs, so they are ideal for motorcycles with limited battery power.

Flasher relay

If you want to add or upgrade the lighting on your motorcycle, you may want to consider upgrading the flasher relay. Motorcycle turn signals use a circuit to detect a burned out bulb. However, LEDs draw a much lower current than incandescent bulbs. That means that it’s possible to fool the burned out bulb detector by adding a resistor. Replacing the LED will require replacing the flasher relay, as well as a resistor. You can also try turning off the burned-out bulb detector, but that looks silly and is not advisable.
