GY6 50cc (139QMB) Flasher Relay

Flasher Relay for GY6 50cc and 80cc Engines

This flasher relay is made for 139QMB and GY6 scooters, giving you dependable turn signal operation on the road. It works silently, so you will need to switch off your indicators by hand to prevent others from being misled. It is one of the simpler GY6 50cc scooter parts to swap in, offering a direct fit when OEM units are hard to find or priced too high.

Operation and Fitting

This relay controls the blinking of your turn signals whenever you ride. A 3-pin male connector gives it a firm, correct connection across different engine types. If your turn signals blink irregularly or stop working altogether, the relay may be the component to replace.

Compatibility

This relay works with 139QMB-based 50cc and 80cc engines, and also with 157QMJ-based 125cc, 150cc, and 169cc engines. When the engine code includes "QM" or "FM", this product is likely to suit your scooter.
