Actually, the de fogs lend them selves rather well to hid conversions, and the stock (not rebased) d2s bulbs will fit within the housing. You do of course have to modify the retainer, and the glare is pretty minimal if aimed properly. They do have a small bit of upward spill because the cutoff is a crossbeam, not semicircle, so some light will pass below the cutoff bar.
The driving lamps are from hella with xenon originally included, but for 600 a set, they're hardly worth it. They also make a variation of these that they refer to as worklamps. It is essentially a halogen version of the driving lamp, no cut off. From most reviews, the shape of the reflector is the same for all iterations of this lamp, even the xenon.
Also, if you want a set that can be flush mounted in the bumper, look at the Morimoto Mini H1. They're bi-xenon, $275 a set, for projectors, OEM ballasts, and OEM bulbs.
Just out of curiousity, what would be the average lumen output for a set of 100w H3s, approx.?
I don't think bothering with the Morimoto's would be worth it...
