What is the correct light bulb?

[try2pas]

I have a 1980 corvette. When I put on my turn signal there is a bulb that lights up on the front side of the side I am turning to. It is a rectangular clear lens that lights the way for the turn. WHAT BULB NUMBER is that for me to go to Napa to get one?

I'm guessing it is going to be a 1156 bulb.
do you have the old one????

If memory serves, your owner's manual has a list of bulbs.

I don't have the old one but I took the opposite site apart and it is the 1156. Thank you.

Turn signal bulb ?

My 79 took a 1157A bulb. A stands for amber!
