Default 68 some lights

I have a 68 that when I turn the headlights on the back come on really dim. When i put the turn signal on they are really slow. My headlights work fine nice and bright. I have tried the flasher with no luck. I have tried a new hi/low switch no go. Any suggestions would be appreciated.

Thanks

The reason they are dim is due to to much resistance. Bad grounds, headlight switch, wrong bulbs, corroded sockets and contacts, wiring thats corroded inside is a few of the things I would start looking at. Hope it helps.

Sixtystyle is right on this. The only thing I would add is a possible short circuit some where on the way to the tail lights. Rusty sockets would be my first inspection though.

My car does this too. Everything is nice and bright as long as the engin RPM's are high, but when I come to a stop the dash lights dim and turn signal slows down. I think it is kinda cool, just a unique feature of an old car. I always though swithing to a solid state voltage regulator solve this. Might be worth trying one of those one wire alternator conversions.

Check your voltage at the battery with the lights off and then on. You probably don't have enough power, at idle, to keep them lite bright.
