Has anybody had this problem? My old 1986 Volvo 240 DL has always burned out rear tail light bulbs, mostly the ones for braking. I have long ago drilled a weep hole in the bottom of the lens to let moisture out, but that did not help. I go through bulbs in days. It is very frustrating. Any suggestions as to what is causing this resistence that burns out my bulbs? and possible fixes??
