Title: Brake lights coming on at night
Post by: dansmith180 on November 05, 2014, 05:52:13 pm
I have been told by a neighbour that he has seen my brake lights on at 4/5/6am 3 or 4 times since I got the car. They all work normally otherwise and I have no other electrical issues, does anyone know what could cause this? Am I doing something? Cheers

Unfortunately it can't be B because my car died overnight a while ago and I had no idea what caused it until now.

Just bumping this to see if a brake light switch solved the OP's problem.

Having the same issue at the minute and really don't want a flat battery as it will drop my Revo map. Only seems to be happening on really cold evenings.

Yes mate the switch solved it in the end but it was a ballache and I ended up replacing the rear high rise brake light. I was just very unlucky and had some stupid electrical gremlins.

Good job Dan, thanks for getting back to me.

£11 from TPS for a new switch, so I'll fire it in  now.

Glad to see you got this sorted...... :happy2:

Real cheap and easy to do. Was doing it on mine and realised it was just the switch? Glad I could help  :happy2:
