I have GEN4's for sale. comes with an HID kit. Only had them for a month.

 

Tommy made his I believe.

 

Update to my previous post!!! I ordered some 3five H7 HID bulbs from theretrofitsource.com and all I can say is WOW!!!!! The light output is WAY better than the other ones I had on. My lights no longer looked crossed eyed like X on the road. They now go II and the light output is superb! For anyone with Gen 4s I would highly recommend these bulbs.

H7: Morimoto 3Five - HID Bulbs from The Retrofit Source Inc

 

Definitely go with a set of retrofits, and Morimoto or OEM style electronics and projectors. You wont regret it, they blow away the Gen4s (and 1,2,3 ) A quality set of retrofits isnt cheap($550 and up) but dont skimp, they will last just as long as your car if you do it right, once.

 

Hate to but in, but I have been reading this and I am curious what is the difference between Gen 1,2,3,4 and retrofit? Is there a thread or a sticky? I have poked around a bit trying to find this but have not been sucessful to date.

 

Go back to the appearance section, look at the sticky by me. It shows the different gens, at least what they look like. If you wanna see retrofits there should be a retrofit sticky as well. If you can afford te extra cost I highly recommend a set of retrofits, the performance of retros is on a whole other level than the cheap eBay projectors. Stick with the 4300k - 5000k color temp, you won't be disappointed with the performance.

 

I just installed the Depo Gen 4s and couldn't be happier. The Depos came from Modern Performance and the HIDs are 4300k Kensun's from Amazon. Cost $255 total. The install took about 1 hour. Easy to adjust. I haven't seen the retrofits in a Cobalt, but mine compare very favorably with my co-workers Acura. I couldn't be more pleased.

 

Can you put here some pic of cut off and light output? Thanks!

 

i like my gen 4's aint no problem with me i run 10k bulbs and as u know not the greatest output but there amazing in the gen 4's

 

That's what I have in my car is gen 4s..IMO they look better then the ugly gen 1 2 and 3 lol..And did I say Halos LMAO!!

 

I don't have a good wall to show up in pics. When driving it is like having landing lights! They light up at least 4 lanes much further up the road that the stockers. Drove around a couple of hours on New Years Eve with no flashes from oncoming traffic. Very sharp cutoff adjusted 2.5" below center at 25'

 

So did anybody have to aim these, or are they good to go?

 

You have to aim the depo projectors when you get them!

 

Ok well, if you see a wall while you are driving at night, take a picture Haha I've been watching those headlight since I have my car and some people told me they were not good quality...

Also, a few pictures of your car would be nice

 

so the retro's wont take the 6k bulbs or it would be pointless? i want kinda a bluish hue to my headlights.
