i have a 2008 xlr base and i live alone:: dumb question is; does anyone knows how i can check if my back-up lights work or not? they only come on when the engine is running and in reverse. the parking brake only works when in 'park' or 'neutral' and the it releases in drive or reverse--and it dosen't do anything in 'acc. mode':: stupid answer is; i put 2x4's under the 4 wheels and barely release the foot brake and it held but i was too chicken to get out of the car and go to the rear with it running. the problem is if i do it with the garage door closed the brake lights overpower the back-up lights and i can't see any back-up lights lit, as it does when i back up in the street. don't say find someone to check it-- i don't know anyone. by the way--how many lights are there? i have 6 i think, i.e. 4 on the side of the license plate [one above the other on both sides] and 1 each on the inside of both brake lights about 1'' wide. i tried useing a mirror but i only can tell the two top lights are on [both sides of the license plate] work,maybe that is why i can't tell when i back up. thanks for any suggestions.
