we're talking about the aux lights right?

The US military has recently started using light force branded lights on vehicles. This tells you two things.
1. Some vendor is making a killing because you know they marked them up like crazy.
2. They've got to be pretty decent.

I know these guys who race baja. They've replaced ALL their hella lights with lightforce lights... both halogen and HID.

They're THAT good.

I would love a pair of their smaller ones in HID, but its a tad out of my range.

The cutoff is pretty good for a retrofit. Looks like DC did their homework on the reflector design.


Joe. There looks like good cutoff on the outside of the beam with the correct pattern cutoff on the top. There does look like theres glare in the center of the beam though. What brand housings are those?

Eh, I guess you could say that. More importantly, I would have to suggest (again) purchasing from a reputable dealer, not eBay or someone you can't talk to over the phone. There is another member on here that had a glare/mis-aim issue with his WK. -Turns out, the bulb he was sold as a "9006" had an arc bulb which was about one quarter inch lower than the stock filament. -So I guess there was a fair amount of homework on both sides, DCx's and my own.


As it turns out, YOU CAN INSTALL HIDs IN STOCK HOUSINGS IF YOU DO YOUR RESEARCH.

Here are some good examples of the glare.




this is a 05-08 era chevy truck with hids in all three housings.

The low beam wasnt too bad (keep in mind its 4:30 in the afternoon with the sun at our backs) but the fogs were throwing a HUGE amount of glare... it was hurting my eyes in the daytime thru a tinted window... thats how bad it was.





9:30 at night. Car on the left is a ford mustang with hid bulbs in the OEM housings. Car on the right is a newer honda sedan with halogen reflector headlights. And the camera cant show how dazzling the hids are compared to the oem halogens.

I have hid's in the stock housings on my 2002 explorer and have absolutely no glare issues at all. It even passed mass state inspection and the guy new what was in there because he asked. He put the truck against the headlight aiming board to see the aim and pattern and was surprised to see that there good to go. I have put hid's in regular rippled housings with bad effects, but have never had issues with a factory clear headlight lens housings.

Certain housings do respond better to hid's but they still need to be aimed according to light output. No housing or hid bulb is exact. They all need to be aimed after installing hid's.

I put some in my mustang with factory headlights and ended up selling them because of glare issues. It had the rippled type housings like these:



The reason is the inner reflector is not designed to spread the light output efficiently, so the lens has that rippled effect to help spread the light output evenly and efficiently. When you add a bulb that creates a crazy light pattern into this type of housing, it gets even worse. There is no aiming to these that could eliminate all glare, because of the rippled housing. Even though you aim them down, the light still hits the ripples and bounces back to the reflector or gets it angle changed and exits the housing.

I put some in my 02 explorer with factory clear housings and have had "no" negative effect with glare. I even had to aim them up a bit after the install. this is a pic of the factory housing:



I've been driving with these installed for about a year now and have "never" had anyone flash there high beams at or been pulled over because of them. It even passed mass state inspection with them on.

I will try to get some pics tonight of the lights in my X.

That being said, I wonder how the Cobra version of the above lens (shown below) would perform with an HID bulb? It has the smooth surface with no outer refractor.

Bumping this...

Don't forget installing HID bulbs in housings not intended for them is also ILLEGAL in most (if not all) states.

I also highly doubt you'll see a (legit) D.O.T. mark on any ebay/craigslist/chinese HID kit.

Actually, its not illegal in that many juristictions. Its sort of a grey area, legally.

And you are correct about the DOT (or sae) markings. If the conversion has them, they're probably fake.

Don't forget: the main reason not to instal HID bulbs in stock housings....because you run a huge risk of melting the housing and starting a fire.

Um, no.

If you're just going to say something stupid, why bother posting.

HID bulbs generate LESS heat then halogens, generally.

like mad rabbit said ... much less heat than halogen bulbs especially upgraded units like fatboys.

my hid retrofit is doing just fine with nobody flashing me or anything. made a lot of adjustments, including making an extra shroud with a cut up coke can welded to the stock shroud
