Many Jeep Wrangler owners have opted to get aftermarket LED headlights. They are a very popular solution to the headlight woes of the Original Manufacturers headlights on the Wranglers. 
Back in August I replaced my headlights with Auxbeam headlights. Auxbeam asked me to try out their headlights so I gave it a try.
Well...I was driving home from work the other night when I noticed one of my headlights seemed to be out. When I got out of the Jeep my driver’s side headlight
I also noticed some flickering, but only on the driver’s side. Which makes me wonder if I properly installed and plugged in the lights. Well, it has been just too darn cold to work on the lights. And my garage is not heated. So instead, I decided to do some research, and ask around.I have come up with 4 possible solutions.
FIRST: Do a little detective work swap the lights to see if it’s the same light or the housing mechanism. Maybe I just didn’t plug it in good enough.
SECOND: would be to try what a former auto mechanic friend suggested and that is to use dielectric grease. You apparently use this on the plug and it’s suppose to help conductivity. Or so I am told. But I also read. The most frequent Internet complaint is that dielectric grease insulates connections, making connections less conductive.
THIRD: Check to make sure my connections are good and not gunked up.
FOURTH: During my research I found that flickering among LED’s is common. I came across what’s called Anti-flicker decoders. I am told the flicker is because the headlight high and low beam circuits have a PWM regulation on them - pulse width modulation. A mode that basically pulses DC power to keep at average wattage. This is not compatible with LED headlights.
