To keep hi/low beam functionality, you'd been bi-xenon projectors, but I'm not sure there is enough room for them to fit. One of the threads showed where someone did come cutting to the area behind the headlight to make a particular projector fit. If I find it again, I'll post it.

I found the thead:

(Look at page 2)
Here is the specific post with pictures:

It doesn't say what kind of projectors those are though.

VIP1: I have seen those pictures before but I'm not really fond of that install or the cutting that was required. The finished product is not up to my standards. I have a set of extra headlight buckets and will look to use a set of Infiniti FX bixenon ballasts since they seem to be the smallest of the bixenon projectors. The price I have seen on them on Ebay are around $80 so it's not too bad. I am probably looking to do a similar retrofit like I have seen others do using plexiglass. Once that work is done, I will be looking into have a harness made to adapt the wiring since I'm not big on cutting wires.
Once I'm done I will do a write-up with plenty of pics.
I think LS1_SS was selling a kit but I can't remember.

(Its also listed in the Lighting FAQ.)
One difference would be that he removed the bi-xenon functionality where as you want to retain it and also his car is a late 4th-gen Firebird.

I actually found that link in your lighting FAQ post. It's going to be tricky to get this to work but I think I can pull it off. LT1 birds just don't have as much room as the LS1 birds, especially since I would want to retain the bixenon functionality.
Would you happen to know if our systems are negatively or positively switched for the high beams? There is a test to figure this out but maybe someone who knows could chime in and let me know. It will be necessary when I have the wiring harness made up so the high beams work.

I recently sold my 97 T/A, but had a design somewhat mapped out for my headlights. I based mine of a another T/A from Camaroz28 forums, it had the sleepy eye mod done. All that entails is moving the stop on the inboard side of the headlight bucket. Full up position, i measured 8in from to of light to bumper measuring straight down. Width is about 8-9in across, and about 5-6in deep. Now, with the sleepy eye mod, i had it to where the headlight opened at 4-5in tall, you have the same width, but now have a deeper recess for mounting a projector in there. This distance increased to 7-8in, plenty of room to mount a projector. I was going to use the Acura TSX projectors as they are one of the smallest sets available. I wanted the bi-xenon feature, so perfect selection for me. So, in all aspects, reduce the headlight height and you gain some room to mount any type of projector in the 93-97 T/A, formy's.
Sorry if that's confusing, but i'll have to look for my drawing i made up this past winter. But, i'd say at minimum upgrade your headlight wiring harness, and relay the lights as well. This way you don't fry your headlight switch or wiring. Just an extra measure for better lighting.

Upon further thought, the high beam can't be ground switched since the high beam and low beam share the same ground. The bulb has three terminals, two positive terminals and one ground terminal. One positive terminal is for the low beam. The other positive terminal is for the high beam. The third terminal is the shared ground for both.
I'm not sure, but why would it matter? Is the ground for the high-beam actuator shared with the ground for the bulb? Probably not, but if it is and the high beams turn out to be ground switched, you probably could easily modify the ground lead from the actuator to be separate.

Nite_Hawk: I have seen a sleepy eye mod done on a white trans am and I thought it looked great and would help with the depth issue. I never got a lot of details about it but I would like to know more.

I have the link some where in my bookmarks, I'll look for it and PM you. That is the car i based mine after.
