I have a 60 T-Bird in process of fixing up (for almost a year) and have ran into a problem I can't understand. The turn signals will not work. The parking/tail lights work. I've replaced the flasher and the turn signal switch in the steering column to no good effect. I've noticed that the driver-side parking/tail light burns brighter than the passenger side lights. As though both filiments in the bulb are lit. Perhaps this is a clue? I am not well versed in electrical, regreting getting involved with an old car. So, If anyone has a suggestion that may save this T-Bird from eternal confinement to the barn lean-to, please let me know. Thanks.

Did you check the fuse and/or connection on the back of the headlight switch. That sends power to the flasher. If that's ok then remove the blue wire from the flasher and test for voltage. If that tests out ok then the problem could be the front parking lights. They often cause the turn signals not to work. If they are ok then I would check the rear lights and the ground wires.

1960 Thunderbirds have a separate in-line fuse holder tucked up, beside the headlight switch. (Don't ask me why.) Click on the diagram below for a printable, more legible size:
This fuse feeds the Brake Switch on your Master Cylinder. If you have power there, the fuse is good.
I tell everyone I can to extend the fuse wires so you can relocate the fuse holder to a more convenient location.
Your steering column is fed from two different directions because the flashers interrupt the brake lights. Follow the wiring diagram from the Steering Column connections:
The Key Switch feeds the Stop (pressure) Switch. The 'switched side' continues to the Steering Column (green wire).
The Key Switch also feeds the Steering Column through a fuse on the Headlight Switch and onto the Flasher Unit (blue wire to the Steering Column).
If you replaced the turn signal plate, you should be very familiar with the bullet connectors at the base of your steering column. All power and light wires can be checked for power right there, with the Key Switch on.
A dim bulb usually means you have a grounding issue. This is common with old cars. I run a separate stranded copper ground wire from my battery to the trunk area, branching off for the dash, power windows, seat motors, convertible top motor, trunk light, fuel tank ground and tail light and license plate housings. This wire can be bare and bolted to the floor in various places. I guarantee you won't have a ground problem again. - DaveMember, Sons of the American Revolution

I remember those big black #2 pencils. That was the only time I ever used 'the big hole' in those Boston pencil sharpeners. Remember that distinctive smell of Ditto fluid?

This turned out to be a carnival of errors. First, the previouse owner(s) broke or cut the front turn signal/parking light wires and spliced them back together incorrectly causeing the wrong filiment to light on the drivers side. That caused the difference in light intensity between left and right. The failure of the turn signals to work at all was due to an unterminated wire at the fuse on the back of the light switch. Once this wire was connected properly three out of four signal lights worked. The passenger side rear turn signal did not work until I traced the voltage back to the new turn signal switch and found that if I manipulated the signal switch by hand, pressing it further by hand than the turn signal stem/switch naturally did, the passenger side rear signal would work. Which means that I must decide if I want to slightly press up on the turn signal stem to activate the passenger side (right) rear turn signal each time I want to signal a right turn or pull the new signal switch out and send it back in the hopes of getting a replacement that works properly. Hope this makes sense to the reader. Tomfoolery.Comment

Tom, I'm glad to hear you got your lights straight and everything is good, now.
