so I am planning on changing my turn signals to LED's. I bought some 1157's as indicated by pretty much every website out there. When I took out the factory bulb, it is definitely not an 1157. There are 3 lugs on the sides. Anyone happen to know what size bulbs they actually are? I suppose I could just change the socket to an 1157 too....but thought I'd check and see what the heck is going on here.
