Peugeot 407 rear brake lights not working

Might be an idea to check for power to the bulbs!!!!.

Thanks for the advice. I had checked the power to the bulbs which I forgot to mention. Anyway I have spent another half hour yesterday playing around with the brake light switch adjustable column. Guess what! I got all the brake lights working. It turned out to be that the brake light switch column was jammed and required some adjustment to ensure that it engaged with the brake pedal correctly. By the way my left bulb which I replaced had blown. No more messages and all brakes working (touch wood) . The car was booked at the dealer for next week. They would have charged £70 to check it on the computer.

I have a simmilar problem with brake lights not working & I think it's causing the ESP to report a fault.
Forgive my silly question but only had the car 2 months. Where the heck is the brake indicator switch. How do I get at it?

Hi the break switch is under the glove conpartment on the passengers side,i changed mine recently

You may think your tail lights are working but the tail light is also brake light. It's a double filament bulb. If your rear windscreen light goes off n on when using brake pedal. It's not your brake switch. So I find it hard to believe that adjusting your switch made all 3 brake lights work instead of just 1. So please guys double check your tail/brake bulb before ripping out all your wires and adding extra earth. All 4 bulbs in each pod run on same earth, so if 1 works it's not your earth. Don't ask me why both brake filaments seem to go at the same time. As I don't know, but it's simple problem, so easy over looked as when you see the bulb lit. You think it works.
