Hello there,



I have 1979 Honda CX500C and it's a thing of beauty minus the fact the brake light is always on when I'm riding. Brakes work fine its just the light that's not working. The strange thing is that when I press the foot brake hard the light turns off....any thoughts or ideas? Do you think its some type of mechanical issue or is that something funky going on with the electronics. Any help would be great!!!!!!!!

Well first you realize that it is meant to stay on low at all times. And then when you step on the brake lever or hand brake it is meant to glow bright.



Does it get brighter when you grip the hand brake? The wiring there is pretty simple. I would suggest that you inspect it. Foot brake switches can seize due to rust and other things in the switch.

Brake light switch may need adjustment or replacement if the brake light is indeed on. It's connected via a spring to the brake pedal, push the pin in and see if it effects the light. If the light goes out when you push it in, it needs to be adjusted. If the light flickers and flakes, it needs to be replaced. If you disconnect it and the light is still on, then the problem lies elsewhere, probably in the front MC switch.



Check out the general info stickied post, you'll find a link to the repair manual, download it, it has the repair and troubleshooting procedures for the switch. Luckily it's more electrical than electronic, it's REALLY simple, as all critical components should be.

Ya I know the tail light stays on but it stays bright like I'm using the break. It goes back to normal running light brightness only if I step on the foot brake very hard.

I wouldn't be surprised if the little rod in the switch is getting stuck when pulled and doesn't want to go back right. Follow the wires back from it and unplug it on one side and see what happens when you pull the front brake lever. If it acts normal then it's most likely the foot brake getting stuck. They sell these foot brake switches on ebay for $5 or so.
