I have the third gen projector headlights and I was wondering if I could put a HID conversion kit in them with out having any problems? Has anybody done this and if so how is it working?

 

cheaphids.com H1 kits fit. i have them in gen 1 and are awesome!

 

are these for the 9007 bulbs

 

go on that website and find the 9007 option, But tbh im not sure if the 3rd gen is 9007 or h1. I know oem is 9007 other than that im not sure.

 

The third gen projectors are h1 bulbs

 

HIDs work fine in third gens, I've had mine in since last year.

 

Triple post FTW!

 

you have to modify the hole that the bulb fits into with a little grinding.

 

My bulbs fit fine.

 

Order the bulbs for the SOCKET of the HOUSING. The projectors use H1 bulbs... so ordering a 9007 kit won't fit. THe 9007 kit should only be ordered if you're using them in the stock housing.

 

So Ill order the H1 conversion kit! This kit wont melt my lense or projector???

 

no. hid's burn cooler then halogen bulbs. ALSO order a 9007 wiring harness from 3bspecs. it will save your stock wiring

 

Order the H1 harness. The battery fed harness hooks into the wiring of the housing's headlight socket for the remote turn on wire... meaning the 9007 isn't compatable. Trust me, I've made this mistake and had to order a H7 plug to splice in place of the 9007 one.

 

hey once i order my h1 hid's for my projectors, do i need that relay harness bullshit since i have an 07 ??? im kinda confused

 

H1 HID kit from 3Bspecialties. Witht he 3rd gens you don't have to modify anything. I have the 1st gens with H1 HID's and have no problems out of them.

 

but do u need a relay or anything, it says for cobalts 07 and up, and i had 9007 hids for two years in stock housing and it was pretty much fine........but idk why it says u might need that relay..

 

Ok Ill order the H1 harness then that way the kit I order will work!!!!!!

 

HIDs need two "adapters"... I think you're referring to #2...

1) The ballast for the HIDs. This should come with the HID kit. It's basically a transformer that ups the voltage from the car's standard voltage to what the HID operates at.

2) The daylight running light relay. This is only needed for cars that use their headlights (not front yellow running lights) for their DRLs. The reason for this is that the car operates the DRLs at a lower voltage than full headlight voltage. This is bad for the HIDs because the ballast then can't up the voltage to what's required for the HIDs.

The quick answer version to your question is I don't remember if the '07s used the headlights as DRLs, but if they do, then you'll need the DRL relay for your HIDs. If they don't then nothing's needed and you're good to go.

 

I'm not sure for the 07's because their DRL's mess with the HID's. I have an 06 and I did not need the relay. Just the plug and play kit and I was set to go.

 

Oh, well there's the answer then. You'll need the HID-DRL relay if yours is an '07 then.

 

you need to order a 9007 harness not a H1. just so ya know.

 

ive had hid's in my 07 for a while with no relay ,everyything works fine, and i am pretty sure i do NOT have daytime running lights which is weird since i see evvery othe r cobalt during the day with them but not mine and im an 07..

so i asked that question tho because i have projectors now and im going to order the h1 bulbs with a 9007 harness correct? and i know i dnt need the relay now..

 

Your DRL fuse may be blown is why. I didn't like mine, so I pulled the fuse and they don't come on now unless the autoheadlights or I turn them on.

To the OP: I forgot about this option. You could just pull your DRL fuse in the fuse box too. It should be in the upper left-ish part of the fuse box by a big relay if you're standing in front of the car.

 

The relay harness is reccommended... but you can run without it unless you encounter issues or want to use DRL. If you're going to not use the harness on the 07+, yank the DRL fuse under the hood. You will only lose DRL function, not the autolamps (Your lights will come on automatically at night or when raining).

As far as modification to the 3rd gen housing, you will need to perform the anti-glare mod (See how-to section) to remove those bright spots that occur in them. Other than that, you don't need to do anything to them as far as bulb sockets go. The return lead will be a little tight when putting it in, but i'll not hurt anything.

 

It should be noted too that if you buy the 3rd Gens from 3bspec, that they will already have this modification and you won't need to do it. I asked a while back about this and they perform the modification to all 3rd Gens, whether they are ordered with HID kits or not.

It's great if you're like me and want to go cheap to see if you like them as-is, but then may decide later that you want HIDs after all.
