Think your bulbs have issues, not sure, would need to be there to test, I have installed LED bulbs on both my front and rear lights, all of them have resistors to the body ground and all work perfect. Not sure what to tell you at this point, I actually have replace all my bulbs with LED's, except my backup bulbs that are now HID's and have Zero problems.
By the way, what bulbs did you install, where did you get them from? make?
