the handbrake light coming on - mine used to come on every now and again. you should look at it as a warning light for all things to do with the brakes. discs need replacing pads need replacing - brake light bulbs gone etc etc i took my dash off at one stage thinking it was earthing somewhere and found it wasn't - then replaced the switch under the handbrake, then the rear disks and it went off. Hi, as far as I can tell my handbrake light is working fine. It is a circle with a "P" in it at the bottom left of the panel. The lights that come on are a Battery shape and above that an exclamation mark inside a circle, it's next to number 1 on the counter. They both come on at the same time, after about 5mins. cheers
