Help with LED taillights

[Dale99]

I posted this in the electrical section, since it doesnt get much action, I decided to post here.

I have been having trouble with the stock right side break light not working constantly. Seemed the turn worked fine.

So I replaced all the stuff with the led circuit board led lights from lmc, kit 37-0342(I got it 2nd hand, but not used). I installed repo housings.

Once again, the left side seems to work fine. The right side, while works every time, it blinks twice then stays on for breaks. Blinks differently for turns(compared to left side). For the power,I tapped into the wiring under the "bed". I soldering the wires together. For ground, I am still relying on the housing to body contact/screws.

Is this how an led works with poor ground? Other ideas?
