Reverse light blinking?

Means your reverse sensor has failed. You can replace it or bypass it. Most do the bypass. Once bypassed though, the reverse light will never come on again. But you will also have full power in reverse at all times. No limiters.

You can also put a switch on the bypass circuit wiring. This way you can turn on the bypass when you like.

Replace the sensor and if you want to override the rev limiters do it with a switch. Just in case less experienced riders get on you machine.
