HID Retrofit - the right way to do it

I just completed a projector retrofit of my NBS Silverado's headlights. I really don't care for simply sticking the HIDs in the stock lights, it's inconsiderate to other drivers and draws too much attention to what you're doing.

Total project cost $150

Here's how I did it -

I used Morimoto mini Bi-xenon projectors from the Retrofit Source. These are made for HID bulbs and fit perfectly in the stock housing with some minor trimming of the bulb socket. I didn't buy ballasts as I had a few sets laying around. Took around 3 hours and the results are above expectations. These are bi-xenon, meaning there is a solenoid inside the projector that flips down when you turn on your brights - so you've now got 4 hi-beams :)

NO glare, clean cut-off, and nobody flashes their brights at you.

Bi-xenon: Morimoto Mini H1 4.1 - HID Projectors from The Retrofit Source Inc

Here's a good guide for how to do it - I don't necessarily endorse the way they hack open the lights, use whatever works for you.

I don't mind people flashing their brights at me. I spent $40 and have tons more light IMO
Actually, since the bulbs are the same and produce the same amount of lumens, I have the same amount of light, except it's all going where it's supposed to instead of being scattered all over the place.

Hey, if you want to light up everything right next to your truck, be my guest. I'll be looking at the road lit up waaaay in front of me.

I wonder if these would work on old body style

i need to find a projector for my low beams. i need to change what i have, they cut off to low/short in front of the truck. this is a great site you gave me, thanks!

Or you could just go to Ebay for $150.00 and buy a complete replacement light that has options like clear, tinted, etc..

I had those halos lens... personally couldn't stand them in all aspects. And as long as you actually adjust your headlights with HIDs they are not blinding... and mind don't scatter light everywhere? They have the same output pattern as they did when I had stock bulbs in... Haven't been highbeamed yet in my truck since I had them adjusted to stock specs. And even if they did scatter, it would probably be better here in PA..so we can see all the deer coming.

Any eBay/Recon/etc. lights you buy are going to be set up for halogen lights, not HID. As soon as you put the HID lights in they all do the same thing - light is too low and scattered all over the place because the focus point is wrong.

The projectors in these lights are cheap crap. If you want to do it right, go with projectors made for HID - either retro fit the stock lights or replace the projectors in the cheap crap with the right ones.

Considering how much $ folks dump into lights, you might as well do it right the first time.

I've been there, done that. Finally did it right.

Unless you buy an HID kit designed to be used in a factory housing. I've had mine in for almost two years and have never had complaints, not been harassed, not been pulled over, and have only been flashed twice. As long as the lights are adjusted properly and designed for the factory light housings, I don't see a problem with them.


Oh, and I see the deer before they are right in front of me also, that way I don't hit them and tear up the truck

Has anyone tried using an oven to take the lens off? most of these on other vehicles are glued on and a few minutes in the oven loosens them up enough to pull the lens off, not sure on our trucks though
 
#16 ·
I tried one light in the oven - followed the guides on YouTube, etc. Set oven to 250 degrees for 8 minutes... ended up melting some black plastic on the back of the lights and got NOWHERE trying to pry off the lens.

I wouldn't recommend it. I used a Dremel and went around the case as close to the black plastic as possible. Sealed them back up with white silicone first, then a top coat of black. If you take your time and clean up the chaff before using the silicone it will look fine. All of the seams are hidden except for a 4" section on top of the light when you open the hood. Rained on me a couple times already and they're holding up fine.

Those look killer... definitely want to do mine.

Apparently people don't understand that HID's need to be focused differently than any halogen bulb and aiming them down further doesn't help much. I had Denali headlights in my 06 to try to get a better cutoff for the 6000k hids I had but it still wasn't that good. Really needed to do a retrofit but didn't know if I was up to the task. I also used to have hids in my fogs but that is really inconsiderate so I took them out.

Also just sticking Hids in stock lights isn't going to do much, it looks like you have more light because it's a different color but really you're just an idiot with annoying lights.

But whatever GIT-R-DONE HIDS everywhere I aint consssserned bout other folks' screw em'!!!!!!!!!!!

So perhaps someone in here could point me in the right direction but I got a set of aftermarket Halo lights but no projectors and put HID's in. I admit the light seems to be a bit scattered but it was worse when I purchased a set of projector halos. So what do I actually adjust to get all the light focused further in front and not so scattered? I have never been flashed for what its worth but my OEM fogs with HIDS seem brighter though

You need a projector housing designed for HID. Sticking an eBay HID bulb in a non-HID projector actually turns out worse than sticking with the stock housing. As was mentioned in a previous post, the focus point is all wrong.

I used the Morimoto H1 projectors, which are designed to retrofit into stock housings - you remove the clear plastic cover, enlarge the bulb hole slightly, and the projector mounts in the existing hole. You can find these projectors everywhere for <$120.

These lights are unreal. Best lights on any car/truck I've driven, including two other cars with HIDs.

I have ANZO projection headlights with 6K hid's and they are fine. Don't know how the focus could be off, the housings are curved to reflect the light outward. The light is then focused by the lens to a specific point. The length of the bulb shouldn't affect that (HID's are long thin bulbs). And different manufacturers of hid's have different lengths, so if what you are saying is true then you have to buy a certain length HID every time and they are not sold by length. The only thing that could be an issue is the lens may be imperfect. They sell upgraded clear lens. I also have 6K HID's in the fogs too and there is no difference in intensity between them and the low beams. I am going to install a set of retrofit projectors in the fogs soon just haven't had time. And lastly I believe I read that there are only 4 or 5 manufacturers of projectors total. All others buy from them.

There is so much wrong with this post. It's ALL about focus point and the length of the bulb. Got a mag-lite flash light? what happens when you twist the focus ring - it moves the focal point of the bulb! Of course the bulb placement has an effect on the focus point! Different manufacturers of HID's have different lengths? Yeap, if you're talking ebay bulbs retrofitted to halogen bases. Legitimate HID bulbs are manufactured to strict tolerances and all have consistent focal points, just like halogen bulbs. Spend 1 minute in my truck and this all makes sense. So far everyone who's been in it can't believe the light output, and I haven't been flashed once, because I'm not blinding anyone.

Exactly, it dips the light output to oncoming traffic. If they're adjusted right, the dip should coincide with the centerline of a two-lane road.

THESE ARE HID's :rolleyes:

^^^^x2 I find my self on small ditches all the time and without the light free floating I would've found myself in a pile a trouble many times

Oh look! See that glass blob inside the tube? That's what affects your focus point:

Apparently this is a self-appraisal? Dude, stop while you're this far behind. I don't even know why I'm wasting my time responding. Guess I'm just a dick who enjoys calling out stupidity.

Let me first state my point of my first comment was the same as yours (fflmlf), trying to give helpful information to others. My first comment wasn't to attack you personally but it apparently did. For that I apologize. The information you stated (better than any other projector) is, I believe, based on information stated on the website you purchased your projectors from. This information, I believe, is purely propaganda. I believe this based on the fact that I could not find any side by side comparison of their projector vs any other manufacturers. If they are that much better show me.

Now let me state that I was incorrect in my statement that the entire length of the bulb is lit. The gas chamber is a larger area than just a filament but still not the entire bulb. Not afraid to admit when I am wrong.

I would like to remove most of the my prior comments but I cannot figure out how. If someone knows please inform me. Again with the idea of making the thread informative by removing the back and forth of 2 adults acting like teenagers.

I also think the housing and lens shape will compensate for any difference in length that there may be in an HID bulb placed in a so called none HID projector. I am going to do some testing this weekend (with pictures and maybe video) to try and prove that is the case. Either way I will post the results. I will also take a photo of my truck lights pointing at a wall and post for reference. As you stated my truck is high so I have the lights adjusted pretty low as to not blind other drives but they still should look similar to yours.

Yeah, you're right, its "propaganda". Lollerskates.

I used the same projector in my bike when I did the retro fit. You should black out the inside of your lights not. Looks good. Not need for all the chrome reflectors now that you have a projector.

Could you post pictures mabye on the road? I for one am curious as to how the real world application looks. I have my HIDs adjusted down to where they don't shine any farther than normal lights and still get brighted sometimes.
