rear lights-i have everything but

I am redoing a basketcase 68 and working on the rear lights. The brake lights work, turn signals work, the hazards work but when you turn on the car lights, the rear lights dont come on.

I checked the brown wires that control the running lights and they have juice. Just must not be enough to energize the lights?

Re: rear lights-i have everything but

The tailight filaments are the ones closet to the socket/base of the bulb. The sockets have one ground as the metal clips on the side of the socket provide the ground to complete the circuit.

So, with stop lights working, ground is good. I'm sure you've checked to make sure you have the correct bulb, 1157, and the bulbs are inserted into the socket correctly and they lock into place. Taking your ohmmeter and checking the filaments between the solder button and socket/base case, you should some resistance of each filament. You can check the continuity of the assembly by placing one lead on the brown wire crimp in the socket and place the other lead on the socket metal clip. However, remove one bulb and check the other as the filaments are parallel connected and you will not find the open circuit for the one bulb. Of course, with power off.

The other item to mention is the socket. The little conductor at the bottom may be too far sunk into the socket and not making contact with the bulb, hence, no light.

The only other possiblilty is corroded wires with high resistance not allowing voltage to pass through through the wire with high amperage loads. A bandaid fix would be to put relays on the lights. proper fix would be to replace some wiring.

Mine had some cheap replacement sockets... 1 bulb would do same thing yours is... found the bulb would go in both ways.

Just something to check ?
