Default Brake light problems ( 58bird )

Only my 2 outer brake lights work when the brakes are applied. The inner 2 only come on when the headlight switch is pulled...........and never indicate stopping....... Could it be

1. My switch at the master cylinder ???
2. The headlight switch ?
3. Incorrecly hooked up in rear???

any help is appreciated

**** all bulbs are new and signal lights and backup lights work fine. Licsense plate lights are not hooked up.

If your outer brake lights are working then your problem is that the green wire is not connected to the inner tail lights.

You also mention you are using new bulbs. Check that you are using the correct double filament bulb 1034 (now replaced by 1157). I have also seen the problem with cheap import 1157 bulbs, for some reason I have yet to figure out, they only will function as a parking light on 58-60 Thunderbirds, not as a brake or turn signal. Make sure the replacement you use is a GE,Sylvania or other name brand made in USA.

There should be two wires comming from each of your inner tailights. The green one should connect to the green wire coming from the stop light switch. The green wire connector must be in your trunk behind the rear cardboard, since th outer brake lights work. If your outer tail light work as brake lights that means your stop light switch works. The inner tail lights do not act as turn signals; only the outer ones do.

I have a green wire with an orange female cap. I also have a green wire with a green female cap that splits into 2 wires.............if I connect the inner taillight green wire to the orange-capped wire...........it becomes a brake light/signal light. The shop manual shows it connected to the outer light...........making it the signal light. This is how I have it. Oddly enough...........I can connect only one inner light wire............because if both are connected.......the inner light burns twice as bright.........as if Im riding down the road with my foot on the brake. I guess where Im screwing up is this...........the black wire coming from the tailights.........and where they are to be run to. I may be mechanicly incline but electrical stuff is not my forte. I found a picture of the wiring diagram and Im gonna blow it up..........Oh LOOK !! another gray hair !!!!

I am not sure why you cannot connect both wires to the inner tail light to make them function normally. Are you using name brand American made bulbs 1157? The import bulbs do not line up right, making the parking light wire contact the brake/signal filament.

This is the wiring diagram for the rear lights:

Thank you VERY MUCH for that diagram..............My father saw the wires and said it looks like someone may have had a trailer hitch connected to my bird (god forbid) with seperate wires for the trailer lights. This may explain all the black electrical tape thats everywhere. Im gonna have to figure out whats supposed to be there...and disconnect all the rest. Ill get it straight.............just be looking at that diagram I know exactly where the problem is. Guess what Ill be doing this weekend :) ?!?!?!?!

My 1960 Thunderbird also had some wiring problems in the rear because of someone had mucked around with the wiring to attach trailer lights. I elected to keep the trailer hitch because it appears to have been installed when the car was new, possibly by the dealer.

Does your car still have the hitch? If not, does the bumper have an unused hole below the licence plate?

This is my 1960 with the trailer hitch:

?????????? I hooked everything up like the diagram and the problem is that green brake light wire. The lights stay bright as if the brakes are applied.....and stay that way. It must have a short or something. AHHHHHHHHHHHH !!!

If you connect a test light to the green wire and put the other end to ground, does the test light only light when the brakes are applied? If so, the problem is the bulbs. Import bulbs do not work on these Squarebirds.
