I have an issue where my the plug end that attaches to the headlight come loose ALL the time and I have to open up the cap and reseat the plug. It's just worn out a bit... or the male end on the bulb is a tad small, not sure which.
You might just check that first. I can't be the only one with that issue and it's an easy thing to check.
Edit: Scratch that. I just went to pull the cap and swap in LED bulbs and noticed that my issue is actually with the female plug. One side of the connector has a wire pulled partially out so it's not making a good connection. I need replace it. You might check your plug wires as well, but I doubt that's it.
