Hey, wanted to see if anyone could help me again. I have the Escalade tail light swap for starts. So my right side light stoped working a couple months ago, thought it was the resistor but it was really the hopkins harness went bad, fixed it and was working fine.

So now on my right light, when I press the brake the inside leds light up but they are dim and flicker. When the brakes aren't on and I use the turn signal, the right inside lights are bright and work fine. When I unlock the car it works fine also. Any idea why when just the brakes are on the inside right lights are dim and flicker? Please help
