Daytime Running Light Issue

[hammerhead2411]

Hey guys, as you can see in the picture, my half of passenger DRL is very dim, the top portion is operating as normal.
Any ideas?
60k miles, just started doing this, no water damage to be clear.

Mine did the same thing. Same side and part of light. I haven’t figured anything out except replacing the whole assembly, which is expensive. I have a 21 XLT with 52,000 miles. I’ve read some things about replacing the ballast but not real sure. I doubt it would be under the power train warranty. I’ll follow to see what you find out.

Same here. 21 XLT with 43K and the subject light went out. Its a bummer being that LED's are lifetime light assemblys and Ford wont cover warranty for it. This is a big let down.

I’ve ordered a “ballast” to see if it works. Probably won’t but doesn’t hurt to try. Of that doesn’t work, I’ve found a few used headlights to get.

I’m having the same issue with my 2021 XLT on the passenger headlight. A member on the f150 Facebook group recommended swapping the ballast from the fully functional DRL to the defective DRL. If the DRL still malfunctions then the headlight is the problem. I’m unsure on whether it’s difficult to get to the ballast.

So... I tried the ballast switch, and the problem was still there. So, I determined it was the actual DRL. I lucked up and found someone on Marketplace with a '22 headlight for $150. Installed in about 15 minutes, and all the lights are good. Problem solved. Hopefully, this one will last a little longer.
