Brake light( no power to the brake lever)


Hello Everyone.
I have a 2001 hayabusa with hotbodies undertail led lights. Last night i noticed none my brake lights were working. I took a close look and found out that rear brake adjuster was off got that fixed, but still no luck on my brake lever, also noticed no power going to it. Anyone had any problems like that or its just me unlucky :banghead: . Thanks
After market tail lights usually have bad grounds as the issue. Have you checked all the fuses and checked to see if you are getting power to the socket?

Yes I checked all the fuses, I know lights not defective becasue they do work, only doesnt work when used on lever .
If there is no power coming from the wire with the red tracer at the micro switch,that is your problem.

Did it work up until the installation of the undertail,or did this just happen?

A good multimeter can surely help diagnose the problem. I think its the relay or the trigger switch that need to be checked.
