[Rosson03]

I don't know if you remember I put those nice LED bulbs in my tail lights just in the top ones not the turn signal and now my driver side rear tail lights are not working any suggestions I've had the bulbs in for almost a month and now nothing oh by the way the little tiny bulb 2 is not working in the tail light

Can you be more specific.

Is it just the parking/running light?

Just the brake light?

Or both?

Top break not the 3rd, during the day on way home, but this morning 5am it was working,

So it is just the Brake (bright) light... the parking (dim) light is working?

Either way...

There are fuses under the hood for LT and RT parking lights.

There are fuses in the I/P junction box at the drivers side end of the dash that are for the Pass turn and stop lamps and Driv turn and stop lamps.

Check all of your fuses with a test light or Multimeter and also check the LED bulbs you installed to make sure they are functioning correctly.

Swap the bulbs side for side and see if the problem moves. If it does it's obviously the bulb.

If it doesn't check the socket the bulb goes into for any problems.

Let us know how you make out.

Also refresh our minds on your specific truck... year, make, and model.
