1990 ford bronco xlt 351w auto 4x4

Discussion Starter · #1 ·
okay, so I bought my first bronco it is a 1990 xlt automatic and 4x4.
my headlight just went out, and the headlight itself is busted. so instead of buying a new one with a new bulb, I would like to buy the led headlights something like this...

I know it for jeeps but I have a buddy who said it would work and has done it in the past on his older fords

now my question is how do I measure the headlight?
right now I have 2 measurements (just for the light not including the blinker)

one is with the chrome trim on and it measures at about 6"x10"

the other is without the trim off and it measures 8.5"x10.5"

what one do I go off of? or did I completely mess up the measurements and need to do it a different way?

if one of those is in fact the correct measurement and I can't find an exact fit, I can fabricate a harness to fill in the void if need be

If you have a 1990 it is a totally different animal. Our brick nose models have very very few aftermarket headlight options.
Buy a factory type replacement. But two so they match.

I mean I got brand new headlights for my 87 and they are very nice. I mean I find them perfectly adequate. But if you are up to the challenge then I guess go for it.
