Brake light activation switch

[TimG427]

I just acquired a new (used) Kirkham and the brake lights work, but you need to mash the pedal down very hard to activate the lights. Is the activation switch in the box under the footwell? Does anyone know if the switch is adjustable?

Thanks

Often it is activated by a pressure switch in the brake system, so that when you activate the pedal, pedal pressure turns on your lights. Look for something in line in the brake system near your master cylinder.

Paul, I see some sensors coming off the master cylinder. I will explore this more. The Austin Cobra club is meeting tomorrow, so I'll pose the question to folks at the get together.

If you have a pressure switch, take a look at Amazon and pick one with a low activation pressure and the thread and electrical push on which matches your present system, so it becomes a simple exchange. The low seems to be 45 lbs, some switches come with 60 lbs for there low you want the lowest you can get.

Sounds great! Let us know what you find out. Good luck.

If on the brake line then it's an easy fix.
Mashing the peddle to get activation is a sign it's failing.
Ask me how I know.
