Hey everyone , new to the site. Joined after finding a lot of useful information. I now come looking for help myself. I own a 62 Impala and i cannot figure out why the tail lights don’t work. I’ve searched online checked out different forums and can’t figure it out. My headlights work, parking lights work. Turn signals on front And rear work. I have checked all ground straps, sockets and bulbs. The harness passes power from under the dash to the back, I tested this with a test light. I pulled out the headlight switch and tested the harness connected to it. I get test light power when I turn on the headlights, parking, when turning on the turn signals even the test light blinks correctly. I have power at the fuse box. I’m stumped. No dash lights either. Help!!! Been going at this for over a week... thanks all

Do you have the right bulbs in your taillights. The bulbs ground via the filament so if you don't have the correct bulbs, it won't ground properly and you won't have brakes or taillights. I believe they are dual element bulbs but that's going from memory. Since your test light indicates you are getting power there, I would start there.

1157's are dual filament and 1156's are single filament. Single filament for back up lights and dual filament for both rear brake/turn lights. Also for front parking/turn lights.

I replaced my regular brake light bulbs with LED.
People constantly telling me one or the other light is out. Added extra ground wires.
Problem persisted. Replaced LED Bulbs again..
Final solution measured the base of the cheap led bulb against a proper 1157 and found that the base of the LED Bulbs was smaller than the original 1157. Went and sourced out 1157 LED that the base measurement matched up to an original.
Problem solved after months of frustration.

No blown fuses guys, all fuses are working. Bulbs are the dual filament 1157 . They do blink when I use the turn signals . Does anyone know if the headlight switch has anything to do with controlling the tail lights ? I only ask because I’ve read that it doesn’t and others say it does on these old chevys. When I pull the knob to turn on the headlights, i get power with my test light to the red power wire which seems to be the constant 12v, the yellow wire gets power when I turn the headlights on fully. Black wire gets power when I turn on only parking lights. The remaining wires don’t turn on my test light at all. There are green, white, orange and purple wires remaining. Thanks for the replys

The tail lights should come on in both the first and second position of the headlight switch. The orange wire on the light switch supplies power to the tail and dash lights. It comes from a fuse on the fuse panel. Do the brake lights work? The orange wire also provides power to the brake light switch. Does the dome light work? Orange wire also powers the dome light.

Just checked it again, I get No power from the orange wire. No power from it at the headlight switch, no power from it at the brake light switch. My instrument lights, brake lights, and dome lights do not work. I checked the instrument fuse looks like a 3A fuse , it’s not blown but I get no power from it either with my test light at the fuse block. Changed the fuse and got the same results.

The orange wire gets power from a larger fuse (9 amp, I think) that may be marked, stop or brake or dome, or maybe clock. The small 3 amp fuse protects the rheostat in the headlight switch that dims the dash lights. It won't have power until the orange wire has power and the tail lights are on. Check both ends of all the fuses, with the test light, it has to be the same.

You sir are a genius! After going through the fuses checking that I get power on both ends I found the fuse that is labeled tail lamps was only getting power one end of the fuse. The filament inside the fuse had a hairline separation I could barely see it but it was there. I changed out the fuse and got power on both ends , now I got instrument lights, taillights, brake lights and dome lights!!!! I just picked the car up last week and haven’t been able to enjoy it yet . I want to get it all working right before I put it on the road. Thank you again everyone for your help!

Silver, glad you got it figured out.

I'm having a brake light issue, as they seem to only want to work intermittently. I took the turn signal switch apart and cleaned the crap out of the terminals... everything seemed to be working fine, then as soon as I got the steering wheel all back together, sure enough the driver side brake lights don't want to work.

Ughhh. Any ideas? It can't be a fuse, because I've seen them all work at some point. It's not the brake light switch. It's either the turn signal switch is shot or wiring issue. If it's wiring, does anyone have any suggestions where to look?

If the turn signals are working, it's not the wiring. The contacts in the turn signal switch are pretty cheezy.

Check the bulb not working for good ground.

Thanks, gents. I have a new switch coming in on Thursday, so it looks like I have a nice project for Saturday.

Thanks for your responses, and shout out to Junky for his help as well.

Was out of town for work and just seen this, sounds like Acardone has you on the right path. Hope that does the trick to get your lights working right 👍🏽

Thanks guys! Installed my new turn signal switch today (pain in the arse), and everything seems to be working properly! Really wanted to keep the factory switch, but the new one is nice and tight...highly impressed with the overall quality and product fitment.

Best of all, next time someone else has a similar issue, I feel as if I will have some valuable input.
