Driver Side Light - Out. DRL working fine.

[zekesview]

So, this is very weird. Recently I added the AlphaRex lights on the truck. Everything has been fine but randomly the low beam and high beam on the driver side light has stopped working. DRL works fine.
I’ve checked the connections and all seem well. I haven’t checked the fuses as I can’t find which fuses independently control each light. (My understanding is there is a fuse for right vs left light.
Also odd that the Rigid lights aren’t coming on - furthering making me feel like this is a fuse problem.
Looking for advice, options, fuse location or general input troubleshooting this.

Could be defective. I've seen at least one instance on FB where someone had the Alpharex installed that went bad.

Definitely crossed my mind. DRL still works but that doesn’t mean the bulb for high beam and low beam don’t work now.

I had an odd issue with my driver side light that was opposite. Still have oem headlights. Added one of the aftermarket grilles with a lightbar and raptor lights. When connecting what I thought was the raptor lights to the wire for the marker lights, I ended up connecting the lightbar instead. Not sure if that made anything different. Anyway, after that, the high/low beam was always on if the truck was on. I've managed to correct the issue by removing the lock on the inside of the connector. I was able to then push the wire closer to the other wire in the other connector, and it's been fine since. I never cut the wire, so I have no idea why it happened.
