I just picked up a 17 f250 and my led Quadbeam headlights work on low beam and when put on my highbeams one of the low beams don't come on,any help appreciated in advance

 

All 4 of the bulbs have both high & low beam capability. It's not like 2 of the bulbs are high beam and 2 are low beam. Sounds like some kind of power interruption to the one light when the switch is flicked to high beam.

 

Are you saying that your vehicle has the "OEM" quad beam LED headlights?

Is your 2017 F250 a Lariat, or above trim level?

If so and I hate to tell you this but, the only way to fix this issue is to replace the entire headlight assembly or both if they have the same problem.

These are not serviceable like the halogen fixtures.

 

The LED lights are not the same, they don’t use H13 bulbs, low beam is the higher LED, when on high beam, the lower one comes on OTH the low beams. This seems like a fuse issue or a wiring fault. Depending on warranty coverage I would have dealer examine first. When they tell you what’s wrong, you can decide how to repair yourself. They will have to check in the IDS what’s working and not working.

 

I appreciate your replys,I guess I'll take it to the dealer or maybe pull the light and put a multi meter on the wires to it when the high beam is on see if it's getting juice
