is there a replacement bulb for a 1056 for my rv? auto stores seems not to carry them, is the 1157 the same. The 1056 has 2 nipples on the bottom, also how about the 1073?
I suspect that you have the number of your bulb wrong. The 1056 is a 32 volt bulb. RVs have a 12 volt system. Maybe you have an 1156 but that's the wrong base?
