Exterior lights and interior lights dim out randomly while driving. The service department at GM says it is normal and nothing they can do. Chevrolet has issued a bulletin regarding this. How safe can it be to drive at night with headlights dimming out?

Night driving under normal circumstances the vehicle a Chevrolet trailblzer ls 2005 has a problem that randomly shuts off the headlights and dashboard lights. The Trailblazer decides to do this totally on its own at random. This causes a potentially deadly situation when on the interstate and your headlights go out and decide to come back on at random intervals maybe aproximately 15 to 20 seconds apart. Several attemps have been made to the Chevrolet dealership to get the problem repaired. Their comment is that they either cannot duplicate the problem or their is a service bulletin that explains the issue. I have done the procedures that the dealership described in the service bulletins with no success. Currently my Trailblazer is being repaired once again at terry lee Chevrolet as of 12-19-06. The last time that the vehicle was in for repair terry lee Chevrolet replaced what they had though was a faulty body control module. Replacing this module obviously did not rectify the problem and on Thursday 12-14-06 the problem once again returned. Since the vehicle is used to Transport my childeren and wife who have been driving primarily at night. I have become skeptical about whether or not the vehicle is safe to actually drive at night because you never know when the lights will decide to turn off by themselves and potentially cause them to be in an accident.
