Appearance: How to: Retrofit True HID projectors in your cobalt
They look great man! I had eyelids on my lamps before I did mine and I was debating doing it but now I know it looks great! Congrats on succesfully creating them! Have any beam shots against the wall?
i dont have any beam shots yet because it was still pretty bright outside when i was taking the pics and the white light didnt show up to well on the white garage... i will get some pics of the beams tonight.
I have a question for ya Merc . Im getting to the point of at least mocking up the wiring . Looking at the stock Astra wiring , the Hella ballasts in this case anyways are getting 12 volt power from the body control module . The power wires run directly to the ballasts with no relays in between . Id like to do the same with my swap and use the power wire from the stock headlight off the BCM and use the stock ground wires . I vaguely remember you saying something about how thats not good . I dont mind making a separate harness , its not a big deal if I have to ...but could you elebaorate on why using the stock power wires are not a good thing .
Thanks dude .
Thanks dude .
I was wondering about the diode between the L/H beam and wondered its exact purpose in the wiring... are there different kinds of diodes or just one? I am doing this to myHHR soon using the bi-projectors from a Infinity FX35. Thanks Merc for making this how-to!
the diode allows you to lower the shields for bi-xenon projectors when the high beams are triggered. just connecting wires from the high beam and low beam to 85 on the relay would cause the shields to stay lowered since power would find its way from the low beams into the line for the shields. the diode makes the power only go one way. which would be from the high beam on the 9007 connector to the relay. It keeps the power from the low beams from triggering the shields to lower.

Ok , now that makes sense then . I didnt know they spiked that much when they fired up . Thanks for the info . OH and hey , I stand corrected on the DS2/ DS1 deal ...you were right , it is a DS1 set up . I just assumed because it said DS2 on the bulb
thanks for the awesome writeup! I used e46 bixenon projectors and ballasts. Found out the bixenon part of these projectors is a little more advanced then it needs to be. Hidplanet forums helped out there. The wireing harness just have brights is pretty complicated since it is a 3 wire hookup. Anyways, they are amazing!
I'm really considering this for my summer project since I have no more school. For those who have done this I have a few questions.
1) Are you having trouble with condensation with sealing them back up?
2) Are you guys getting a good aim out of them? Like the perfect crossover beam thing?
3) How hard is it to get the wiring done and can a noob basiclly do it?
4) Do the hi and low beams run off the switch in the car like a typical cobalt?
Thanks for your help. Now just to get money and a junkyard to find a decent bi-xenon and projector deal.

1) YES, I did, i had to re-dry my driver's side at least 3 times and seems fine now
2) Seems fine, I could have made it better if I wasn't living in dorms at the time i was doing this project. Didn't have a good area to see how they were aiming.
3)Wiring isnt hard but depends what kind of projectors you get. Im pretty electrically inclined so i was fine, but I wouldnt recommend it if you can't read schematics. I had to make a fairly complex but basic circuit for my high beams because e46 bi-xenon projectors have a 3 wire hookup for high beam functionality
4) Yes
feel free to pm if u have any other ?s

I'm really having problems w/ the headlights fogging up. What did u guys do to seal up the back and the main seals? I used clear silicon in the little squeeze tubes from lows. Any recommendations or help? pm me, thanks
This is worth a try as it worked for me once , and you wont have to pull apart your headlight lenses again . Use permetex window sealer . Its in a smallish blue tube , and its made to seal up the seals around windsheilds . Its like silicone , but its not firm .....it has the consistency of saaaaaay .....pancake syrup . Lay a bead around the entire perimeter of the headlight right over the silicone thats already there , it should flow into any areas where it may be allowing moisture in . Obviously , make sure to dry the inside of your headlights out completely before sealing them up completely . If any water is left in there , it will take 4-ever for them to stop fogging up .
