      Hi Kevin, glad to help! A brake light problem on one side is most often a bulb or socket problem. I would suggest that you to take your vehicle and get it thoroughly checked by a certified mechanic before buying any parts that may/may not solve the problem.

  • Q:

    I have a 2004 Chevy Impala and lost all taillights and brakelights. I've checked fuses and bulbs all are fine. What could this be? I would love a schematic emailed to me if possible

      It could be a number of things causing this. Unfortunately we are unable to diagnose what is wrong with your vehicle without being able to be there with your vehicle. We highly recommend taking your vehicle to a reputable shop to have them take a look at it to determine the cause.
