Bulb # for 12 volt on brake lights/taillights

[steveplym]

The bulbs I have for the taillights and brake lights in my car are #1154. Is this the right # I need? I have both taillights, brakelights, and turn signal on the right side, but I only can get the taillights to work on the right side. I'm thinking the contacts on the bulb are not touching the right contacts on the socket. I tried to change that by seeing where the bulb contacts sit when turned into position, then pulling out the plug socket and readjusting the contacts.

That worked on the left side, but I still can't get it to work on the right side. I'm thinking ground, but I even put a separate ground wire on the socket and ran it to a good ground on the frame. No good. I have power coming from the brake switch as it lights up my test light on the high side.

1157 is 12 volt double filament. offset pins.

1034 or 1157 are both 12 volt double filament with offset pins.

Thanks guys for the info. I didn't realize that 1154 was a 6V bulb.

Hey Steve, I used an 1176, or 1178, I am not sure, but they are 12 volt with the pins side by side. You have to try them to make sure that you have them in right, tail light to tail light, brake light to brake light. Tony C

This got me thinking about other bulbs I may have missed. The under dash bulbs are #63, what is their 12 volt equivalent?

Is there a chart somewhere that will crossover the numbers for 6v to 12v?

Never mind I just found one. This may be useful for others too, I'll post a link.

That chart was very helpful when I went to the auto parts store today and purchased the bulbs. Got all the lights working and turn signals too.
