The amber warning light for the brake lights in the back keeps lighting up for a split second whenever i press the brakes. I changed both bulbs and greased the socket to no avail. Upon backing up to a large window i tried to find out which light is the culprit by pressing the brakes and looking at the reflection. The result is that both the passenger and driver's side brake lights as well as the 3rd brake light in the back window all delay about a tenth of a second which in turn causes the warning light to activate for the same amount of time. The delay doesn't really bother me but the amber idiot light is very annoying. Any ideas on what needs to be changed?
