Glad your noise was just a bulb, when I worked at Sears auto center, we had a customer come in and got new shocks and struts. A short time later he came back furious. he was calling us every name in the book. We pulled his car on the rack, checked the shocks, exhaust, spare tire, all was nice and tight. no source to the banging noise. Somebody asked " Anybody check the trunk???" Well, we found his noise, his bowling ball had come out of the bag, and was rolling back and forth loose in the trunk. SOB never did apologize for the nasty things he called us.
