70 Tail light problem

I went to put my new LED taillights in today http://www.quadratec.com/products/55213_0019.htm , and after i hooked them up the passenger side works, but the driver side does not. I traced the wires back to see if i could see an obvious flaw in the wiring but i couldnt. They both worked before we painted it, now it wont. If any of you have any help that would be awesome.
Thank You

lost the ground maybe, thats where i always start with lighting problems.

 

Isn't there a special flasher unit for LED lights? Maybe nothing to do with your problem. You have no power at all and no function at all on that light?

 

I took a look at the light in your quadratec link and also at the installation instructions. I will caution you on the color code for the wires per their instructions. They show the Black wire is for the Brake/Tail part of the LED bulb but this will not work if you are using a 7 or 8 wire turn-signal switch. It should be Black - Brake/Turn. As shown the white wire is your ground.
