I have a 2021 F150 STX4x4 supercrew42 cab. I have just halogen lightbulbs and I hate it. My question is what would it look like if I got LED bulbs to swap out. Would it shine brightly like some do? Or would I need to get the entire headlight casing unit?

 

I got these in my STX

You can do it quickly by partly removing the covers inside your wheel well. They are fastened by some "plugs".
Twist out the halogens and replace them. About 10 minutes per side.
Very happy with these bulbs.

 

Can you send a picture at nighttime what they look like? Curious. And thanks I will look into these and see if they work for me!

 

I have no pictures, yet.

 

Did this require any special adapters? Or the H1s you got just plugged right in?!?

 

Nope, plug and play

 

Auxito led, this is low beam only. Not brand specific, any decent led bulbs will have this kind of light output. Just be sure to re-aim your headlights after the swap.

 

How would I know if a h1 or h11 works for my truck? It’s a 2021 f150. Having a hard time knowing which one I need to get to make it work?

 

The bulbs your truck uses should be listed in the owners manual. I believe stock halogen bulb numbers are as follows:

Low Beam - H11
High Beam 9005
Fog Bulb - 9140

 

Plug and play, very bright. You can click the link below for more product information.
