Hey folks, been a while since I have been here and I have a total beginner question. What is the bulb number for a rear turn signal in a 2001 3500? I seem to remember it is something like 1152 or 1157. I have one that is bunt out and I need to replace it. It is currently -15F so I don’t want to go take everything apart just to find the bulb number but I need to buy 1 tomorrow.

Thanks for help.

 

Wish I could help out, 1157 seems like the correct one, dual filament....buy 2, the other one will go out soon....

 

Its either 1157 or 3157. 3157 is the "wedge" base. Just going from memory when I was replacing backup lights, I believe it is the wedge base, so 3157.

 

3157 according to the FSM
