2021 XLT FX4 Halogens - Help!

Thanks guys. I’m installing them today. Did you have any issues getting access through the fender wells?

No issues after you remove the top screws on the wheel well liner for access. I actually just remember removing the whole liner. I remember having to loosen the little screw on the high beams to adjust where the light twisted into the housing. Going for that straight up/down, diodes on left/right.

Thank you.

It’s a tight squeeze! The arms will hate it.

I bet! Should be interesting.

Yeah just turn your wheel to the side and take out the 3 or 4 4 or 5 mm bolts. Kinda gotta tug/fold the liner over to the side but give you enough room. You either have enough room for one hand and a view, or two hands and no view.

Again, make sure you test them before putting it all back together. The plugs fit both ways but only work one.

Thank you all! Great info.

Well, life got in the way today so I will be doing the install tomorrow.

Well no good deed goes unpunished. After considerable effort trying to get access to the factory bulbs - and a trip to the hardware to get a tool to remove a plastic retaining clip holding the wheel liner firmly in place -I find out that the bulbs that were sent to me apparently are backwards from what they should be.
I removed the factory low beam and then pulled the new LED low beam out of the box and after working to get the ends matched up, I find out it will not plug-in at all. Arrrgh!!!
When I looked closer at the plugs I noticed they are not the same. See the first picture.

The bulbs from ALLA that were marked ‘low beam’ have a plug-in that matches the factory high beam bulb and vice versa. Has anyone else experienced this? See the second picture. In that second pic, you can see that although the plug end matches the factory Low Beam bulb, the tag on the new bulb says High Beam.
Advice?

Been awhile since I installed mine. I remember that the manual had a misprint saying the low/high beams are bulb size ***, but in reality what was listed for low was really high beams & Vice versa. So for your issue try putting them were the wire harnesses click have the diodes Parallel to the deck/ground & see how it turns out. I think this happened to me but, 1.6 years has passed.
