HID projectors
I posted this in the 1st gen section, but figure a) other gens might want fixed or sleepy HID lamps and b) the geek quotient is higher in this section, so some might just want to see neat electric stuff 
If someone *does* make a fixed-headlamp kit, or even a sleepy-eye one, these HID projectors will fit once you take the shroud off (kit was originally for a 7" round, but is designed to sit 'forward' so the back only goes as deep as a stock sealed beam... this means the front bubbles out and wouldn't clear the opening in a stock flipup lamp)
They use Philips bulbs and ballasts (not shown)
I first took the main shroud off to see what just the projector was like. Here it is next to a DVD for size comparison (no cracks about the movie - I happen to think its hilarious).
Note that everything is sealed plastic, from the D1S base cover to the glass projector lens retainer:
The shroud was attached with 4 screws - each of the screw holes has a brass insert for threads (as opposed to threaded plastic holes, in which its far easier to strip the threads):
The outer lens on the shroud is clearly marked with DOT compliance, and HG to indicate it's meant to contain an HID projector:
The grey cap on top is a vent to allow heated air out of the shroud while maintaining a water resistant seal. In this shot you can see (from left to right) the plastic cap that encloses the D1S bulb, the projector body, the electronics sealed in the black box mounted along the bottom of the body, the shroud bezel with grey vent cap, the spacer ring, the metal retainer ring (with O-ring gasket inside, not shown), and the clear (non-fresneled) projector lens.
a front view of the assembly, minus the shroud:
I took off the metal lens retainer, and here I'm removing the O-ring gasket that keeps water out of the front of the projector (the back has a plastic cap, as seen in the pics above):
Here's looking into the projector with the lens and spacer ring removed. This is a bi-xenon unit, and you can see the simple vertical solenoid that pushes up the step-pattern shield for low beam (remember, the beam flips upside down while passing through the lens):
and from the side:
