Fairly rudimentary problem I’m having here. I have LED headlights and just the left side keeps going out. Not sure why both sides wouldn’t be the issues, I’m running the same bulbs in each. What should I look for?

Are you switching bulbs to make sure it's not a wiring problem on the left?

Yes I have switched the bulbs. So it is a wiring issue. But previously I had the same bulbs in for +1year. Now all the sudden left side is burning through bulbs. What is a good trouble shooting process for the wiring?

It's burning through bulbs or just cutting power to one side? Are the bulbs dying on the bad side from whatever the issue?

Burning through them, a new bulb will work for a few weeks. So I’m guessing it’s some sort of voltage issue. Right?

I would think the fuse is still intact, try replacing it with the same amp rating fuse and if see the bulb lasts longer.

Check that the connections are tight. I had a loose connection on the positive connection to the lamp. It wouldn't flicker, but i could tell something was wrong due to black marks on the bulb side of the connection. I replaced the terminal and all was good.

Okay I will try that out. I’ll let you know what I find out.

The connection looked good, but I will check it out again and make sure nothing looks burnt out. Thank you for the input

Get a multimeter and measure the voltage on both sides. Skin oil from your fingers can shorten bulb life.
