On my 79 Elco I'm putting 67 Firebird taillights in the tailgate. What's with the two side marker type lights for the one light? There are 4 wires for the 2 lights, I want to switch to a regular 1157 socket with 2wires. What do I do?
So I can use an 1156 socket, and delete 2 wires from one of the side marker lights??an 1157 socket will need 3 wires... 1 for running light, 1 for brake/turn, and 1 for ground... side marker lights are just that, single element, either on or off....
an 1156 bulb is a single element bulb that looks like the 1157, but works like the marker light
if you don't want turn signals or brake lights, sure....So I can use an 1156 socket, and delete 2 wires from one of the side marker lights??
this is your 1157 taillight/brakelight bulb... 3 wires: 1 runs your taillight at low wattage and powers 1 of the filaments, wire #2 runs your brake/turn and powers the second filaOn
if you don't want turn signals or brake lights, sure....
On my Elcy I have the 3 wire 1157 socket then the 2 wire 1156 back up light, then there 2 side marker type lights with 2 wires each that are the third taillight, that stays on as long as the lights are on
you should be able to run your existing wiring to new sockets in the new taillights, and not have to worry about killing the side markers for the wires... maybe I'm completely misunderstanding what you're doing, but I can't get my head wrapped around why you want to use only a 2 wire setup, and not use the existing wiring for the tails...
ment, wire #3 is your ground
this is what your an 1156 bulb/socket looks like: 1 wire runs the only filament, fixed wattage, bulb will only glow at a single brightness
your side marker is just a minature version of the 1156 bulb with a flat base, and only has a single brightness...

I want to run regular taillights. I just need to know how to change the 2 small lights for a regular socketare you planning on deleting your existing taillights and running all functions on the firebird tails? or are you just going to hook up running lights as a showpiece? I guess that may be where my wires are getting crossed, so to speak...
