Hi, I've done zero work on my new-to-me '97 C10 except change the windshield to a Madstad. But one of my brake light bulbs went out recently forcing some DIY maintenance. I replaced it with a Honda car bulb per a search on these forums, but I can't get the new bulb or the old one to kick brighter when I hit the front or rear brake. Essentially, all I have are tail lights. Is this a relay issue? Anyone else have this problem over the years? I have the factory repair manual. Thanks!
