9007/9008/H13 Conversion Harness Pigtail Set
Here is the write up I did when I converted mine.

I finally did my headlights on Saturday. Everything went pretty well, got it completely done in 3 hours. I'll post a few notes after the photos.
Before:


Tool for unwinding the headlight adjustors:



Driver's side cut, cleaned up with a grinding wheel at the end:

Passenger's side before:

and after:


Stainless hardware:

Test fit:


Done:


For the bolts, I used:
(4) 1/4-20 X 3/4 BUTTON HEAD ALLEN BOLTS (STAINLESS STEEL)
(4) 1/4 X 1 FENDER WASHER (STAINLESS STEEL)
(4) EXTRUDED "U" NUT 1/4-20 SCREW SIZE (CTR. HOLE TO EDGE:17/32")
I got the hardware from Allen's Fasteners online. Dealt with them several times and they are awesome.
Notes:
1. Don't use a fender washer larger than 1" OD. It will not fit flush with a larger washer.
2. The Extruded "U" nut I used was the perfect center hole to edge length. They make deeper nuts, but they won't fit as cleanly.
3. My headlights had bulbs, but no marker light sockets or turn signal sockets. Turn signals still fit fine. Marker lights do not. I will be ordering (2) sockets from LMC truck (Part # 47-0431) so I can install the markers. For the time being, I just have the old sockets in there to plug the holes. They do not fit well and there is not way to plug the connector into the socket. The sockets do use the same plug adapter from the wiring harness, so no worries there.
4. I knicked my rad core support in a few areas. I made sure to touch all of these areas up before re-assembling. I don't want any unnecessary rust.
5. I used my air die grinder with a 3" cut wheel to remove the header panel. It worked well, but I've heard that a roto zip tool is even easier and probably gives a cleaner result.
Riff Raff did a nice job with the conversion harnesses and I used there how to written by a member on FTE. Thanks guys!

A word of caution.... these lights do look better than the 99-04 in my opinion, but the light output is not increased. If anything, the 99-04 housings actually project the light better. As a result, people have been doing HID retrofits. This seems to be the way to go. LED bulbs do not really help because the 05-07 lights have a crappy lens shape.
All that being said, it seems like the biggest improvement you can make is doing an HID projector retrofit.
You can make them yourself with a kit from here: https://www.theretrofitsource.com/co...rsal-kits.html

when I did mine (on my 2k Super Duty supercab 4x4 V10), I bought the headlights from Headlight Depot. They came with the conversion harnesses and instructions, tho I had to cut more from the resin header than the drawing indicated. I used a Dremel with a cutting wheel to cut the header. Mine are fully adjustable, which was a good thing as they were aimed WAY too low. I took quite a bit of time on the install... cutting, then fitting, then cutting some more, until I got the fit right. What remains of the header is a bit on the flimsy side, but I believe that if you go to the '05-'07 header, you'd need to go to an '05-'07 grill & bumper as the location of the cutouts for the grille clips are different from the '99-'04. There's a number of ways to "skin the cat"... it all depends on how far you want to take it.
On OEM housings, there is a vertical adjustment. It is the external Torx screw sticking up at the right side of the photo. I did not have to adjust mine.

In my opinion here is the cheapest way to do it and i learned this for experience. Get eBay lights you like (mine are eBay lights) and then get the HID parts from the retrofit source, if you look into their close out options you can usually get them for much cheaper by bying the piece parts vs the whole retrofit kit ($300ish itself). The parts total i have in mine is roughly $400-500 i can upload light outputs this weekend maybe if i hook up the fuse panel again.
Parts Breakdown.
Headlights: $150
Clearance D2S projectors: $35
D2S HID Kit: $160 (depends on options)
Projector shrouds: $20
Total: $365
I upgraded the HID system and got 55W ballasts and better bulbs which is why mine is more expensive. I started the retrofit myself but realized i bit off a little more than i could chew but i also didn't have the time to just sit there and get it perfect the way i wanted.
eBay headlights wont matter because if you get new sealing material then they are sealed just as good as OEM lights are at that point.
Also adjusting is just as easy because the projectors are mounted the the reflector housing so you can retain the factory adjustments for vertical adjustment. Most projectors just screw into the hole for the Halogen bulbs but i tried to get too crazy and dug myself a grave causing me to have to ship them out lol. If you screw them in then there is no left right adjustment it is aligned by the housing but if you go crazy like i did and cut out the back of the reflector you need to align and epoxy it in...dont do what i did i ended up getting a new light and having it done.
Also you dont need the conversion harness for the different headlight bulbs you are basically using a custom headlight system so you can get an 9007 to HID harness vs getting a 9007-9008 harness. Overall its a little more expensive but the output is so much better (and legal) its well worth it IMO.

Also do not get 55w ballasts with 4300k bulbs it will turn them yellow (3000k color) which is what you said you don't want.
Also keep in mind the bulbs have a shorter lifespan with higher wattage ballasts so it's a trade off 55w gives off more light but die sooner (20% faster roughly) vs 35w less light but longer lifespan.
I did a ton of research when I did this lol I'm trying to remember if I said everything.
