I agree with you completely Brett. I worked a few co-op sessions during
college with R+D at Osram Sylvania in NH. Most of my work was with neon
lighting (brake lights and turn signals not like what you are
thinking). Some was with HID. This was in the mid 90s when they were
yet to be on any production vehicle (I think BMW was first?).
Sylvania provided several sets of converted PIAA off road pencil beam
lights to Ford for the Baja race in 94 I think. The HID pulled only 42
watts verses the 150+ they were running per light. They could see
farther and had no alternator failures which I guess were quite common
at night. Also like Brett said fuel usage was reduced especially with
the number of lights they run at night. Since HID is a life of the
vehicle product the lack of filiment is perfect for the shock and
vibration of off road racing.
Kind of got off topic there, sorry. Back to the thread at hand I think
it just depends on what you want out of them. If what your car looks
like to others on the road is important than they are a deal. Much
cheaper than HID. If you are looking to improve night driving your best
bet is Euro highlights. I am such an addict that I ran H4s in my '88
