I cannot for the life of me find the front brake light switch on my '81 XS400. I have drums on front. The manual says that the front switch is controlled by hydraulic pressure, but that appears to be for disc brakes only. It makes no mention of front drums. The front drum appears to have mechanical linkage only.
Do only the rear brakes activate the brake light? That doesn't seem right.
