I was poking around in my owner’s manual the other day and it says the correct bulb for the parking/turn signals is a 1034A. I have had 1157A's in there forever. I went to the local AC-Delco parts store and asked about 1034A's. The guy looked on his computer and said no one in the city stocks 1034A's. He asked what kind of car I had and after I told him, I could tell from his body language that I had been 'dismissed' and that no other helpful information was forthcoming. I'll probably try a NAPA place later this week, since they are usually willing to look things up the old fashioned way - in the manual. In the meantime, what is everyone else using? I haven't had a problem with the 1157A's over the years, but I don't want to use a bulb that is not the right one for the application. Did the 1157A supersede the 1034A? Thoughts? Opinions?
