LED Headlight retrofit!

So as some as you asked for in another thread, I'll go ahead and post some more pictures and explain how I installed these headlights:

Into here!

I probably should have taken pictures while I was working on this but with Christmas looming and family arriving, I had to get these installed and working as soon as possible, and skipped the pictures :emb: But worry not! This was a simple retrofit, and works great so far! I started by pulling the stock headlights out and taking a look at how they mounted to the body. After seeing how well the 3 ball-post mounts worked on the stock unit, I decided to just mimic that layout with 2 metal brackets attached to the new LED housing.

Screen Shot 2016-12-27 at 8.27.37 PM.png

I measured the distance from the desired new-headlight position, to the plastic housing with the 3 mounting posts, and found a metal framing strap (as a contractor/finish carpenter, I have a lot of these laying around) that just happened to be the perfect size to be bent, drilled, and fitted to the new headlight unit.

Screen Shot 2016-12-27 at 8.26.51 PM.png

I cut two equal lengths of strap to mount on the outsides of the new headlights to attach to both the top and bottom mounting posts. This allows the new LED light to be adjusted by the factory top post, which aims the housing up and down. If I can recall correctly, the bend is at exactly 2" for both the outer and inner brackets.

Slight trimming is needed on each bracket to clear the plastic housing mounted to the body.

Screen Shot 2016-12-27 at 9.08.41 PM.png

I utilized the original ball-mount-clips and mounted them to the new brackets with some small machine screws and locking nuts. I then mounted the brackets to the LED housing with four 5/16-18 X 3/4 hex head bolts.

Screen Shot 2016-12-27 at 8.26.24 PM.png

And thats that! As soon as you have the brackets done, the hardest part is over! The next step is wiring it up, but unlike me, try and do it without blowing 10 fuses!:shame:Start by pulling fuses 40 and 41 as to not blow them while installing the new lights. I learned these lights alternate the ground to enable the high beams, while the H3 does not. I didn't have the time or patience to figure out how to get the high beams working, so I wired it up to enable the low-beams and DRL's to run simultaneously. Thankfully, my headlight units came with 2 adapter cables, one for each light, and had a plug receiver that was exactly the same as the stock headlight bulb!

Screen Shot 2016-12-27 at 9.08.49 PM.png

After simply plugging them into the H3 headlamp bulb connectors, I connected the White wire from the adapter to the brown (ground) wire going to the LED headlight. Then, after about 4 blown fuses, I found out the blue wire on the adapter needs to connect to the blue wire going to the headlight. In conjunction to that, the Black wire from the adapter ALSO has to be connected to the blue wire going to the headlight. If you notice the yellow and green wire below, that is the positive leading to the DRL. I connected this to the blue/black conjunction to run the low-beams and DRL's simultaneously. The black wire leading to the headlight, is the wire that activated the high-beams. If that wire is touches the blue wire powering the low-beams, it seems to short the system. So, I simply cut the wire and isolated it to make sure it cannot short the system out.

SO, the wiring goes as follows with this particular adapter:

WHITE -> BROWN
BLACK & BLUE-> YELLOW/GREEN & BLUE

Screen Shot 2016-12-27 at 8.25.51 PM.png

After this, the headlights will work perfectly! They will automatically function just as the stock ones do, except you will not have any high beams. And this is where the next issue I had came into play. If you went to activate the high beams or the flash-to-pass (or just bumped it on accident and found out the hard way), it would blow both headlight fuses. Due to the relay alternating a wire other than the ground, it blows the fuses and leaves you with no lights. The simple solution I found to this problem:

Cut the wires that activate the high-beams and flash-to-pass until I can re-wire the relay and have it alternate the correct wire. Pulling the relay will stop the headlights from functioning altogether and is not an option.

SO, under the dashboard on the drivers side, you will look up and see a big grey and blue connector. There is a pink wire (don't worry its the only pink one in there) and a light blue/white wire (its a light blue wire with a white stripe) Those two wires are connected to the signal stalk and activate the high beams. Cut those two wired to disable all high-beam action, and you will not blow any fuses!

Screen Shot 2016-12-27 at 9.48.50 PM.png

And thats all there is to it!:giggle: I still want to paint my brackets and get the relay wired correctly to enable the use of the high beams, but for now the most important thing is they work great and are better than the stock lights! Thanks for reading everyone and Happy Holidays!

Needs moar output shots. You know the useable light that these things may or may not produce to help us see at night.

That would be much appreciated.

Something like this maybe.

I haven't had much time to take any pictures of the light output, but after driving around at night a few times it's definitely better than the stock headlights. It's not quite HID coverage, but its still pretty good. I'll try and get some output shots this evening

Wow! Chris very nicely done. I like the look. How much were the lights and what brand? Apologies if this is posted elsewhere...

I was able to snap some output shots with my phone this evening, but forgot to unplug the Christmas Lights...

The two spots up high are from the DRL strips, which I haven't adjusted perfectly yet. And I bought these headlights off amazon for around $150 if I remember correctly.

Putting an led bulb in your factory headlight reflector will cause glare to on coming traffic even if your brights aren't on. You don't wanna be that guy...

Here is an example of the glare from factory housings vs actual projector headlights.
It doesn't matter if it's led, halogen, or hid bulbs, that all need projectors.

You can't just stick in a new hid, or led bulb in your factory housings and be good to go..

So I missed this thread a while back but glad I found it.

I bought these exact headlights for the Early Bronco I had for about a year... but long story short I had to sell it but I still have these lights.

Are you still happy with them?

The ones I have come with an H4 plug right off of the light but they also came with an H13 adaptor.. so I am hoping that I won't have the same wiring issues as you did and that it will be plug and play (I will check tonight)

What did you do about the gaps around the light (round light square hole).

Thanks!!

I am surprised it alternates ground, but I think it can be resolved with piggy back relays ( car switch with will engage relays instead of light itself, some diodes may be needed to prevent feedback)

I love them so far and they've been working great! I haven't gotten around to re-wiring and hooking the hi-beams up as I moved recently and life has gotten in the way, but I'll get around to it eventually... In regards to the gaps around the light itself, I haven't changed a thing, and let the air flow right on in.

Yeah I had hopes it would plug and play but of course it never goes that easy. Piggy-back relays seems like the best option to me, and I'll have to look into the feedback issue

Did you ever finish the wiring so you have Hi Beams? I need to replace the cans for mine. When I bought my H3 it was used for a fleet service and they drilled holes on the bottom of each headlight can for strobe lights. TIA.

There is actually a way how to wire these 7in headlights without doing any wire cutting. Check out my complete video on how to install 7in lights. Plug and play and no permanent modifications.

not necessarily... it depends on where the focal length of the new lamp is. a company worth its salt will build the replacement to replicate the light emanation & pattern of the halogen it's supposed to replace.

i used these on my wife's H3, and they turned out like this:
compare h13s.JPG
beam low.JPG

same pattern as the stock halogens - only brighter (and forgive the white balance - these're 6500K, which is slightly blueish white to your eyes). it just takes enough research to determine the well-made units & the time/understanding to install them correctly.

nice add - and while i personally appreciate people doing their own research & adding/requesting additional or amplifying data to relevant existing topics once they find most of what they're looking for... however i've seen some dudes get just short of crucified for responding to posts more than a couple weeks old & told to clutter up the archives with their own new thread. that's apparently just the rules around here.

I just finished watching the video posted by Acer4Lo. I learned a lot thank you. I just bought my Alpha yesterday. Starting the mods. First is the headlight conversion. I checked Lazed Designs and they are out of stock right now. Has anyone tried any other 7” housings to see if they can make them work? I was thinking of buying two housing from Amazon and seeing if I can make them work

If you just got it whats the hurry. I'd wait 4-6 months to see if LD's come back in stock. They would seem to make it easy or at least easier to do it. Move on to another mod first
