...I may completely out of my mind... But every site I've looked at, AND the owners manual indicate the front corner lights take a 3157A bulb.
I bought a set of Autolumination 3157A replacements for the front... showed up, looked good, pulled the corner light off, pulled the bulb out. ...they are TOTALLY different. Bulb in my aftermarket clear corner is round with offset contacts. Looked at the stock lens... round with offset contacts. Looked at the 3157 for the turn signal in the tail light, it's flat, looks just like the Autolumination bulbs. Went down to Checkers, said, "I need front corner bulbs for a 2003 Tundra." "Oh that's a 3157A. Went over, grabbed a pair of silverstar 3157's, flat.
Has anybody else encountered this? What is the actual bulb type in the corner light and can you change out the socket on the harness to accomodate a 3157?
