Interesting, keep us posted. One thing Iíve noticed is that on my blown H3s, the filament appears to be ok and connected, although the glass is discolored. That seems odd to me and I donít know where the failure is. Seems like if the filament is still intact, the bulb should light up.
Since the foglamp subject has come up again, I will mention that a few months ago I drilled a ľ ventilation hole on the back of one of my housings to see if cooler temps inside the housing (at the expense of moisture) would help. My tbird runs H3s on a ventilated housing, and the bulbs last forever, so I gave it a shot. No dice, it did not help and as a matter of fact the bulb life seemed a little worse than the sealed housing.
Iíve verified that the harness and feed wire are not getting hot, so I donít think ití* a wiring problem. I guess a bad ground could overheat the bulbs as well. My guess at this point is that the small plastic housing is not capable of dissipating the heat generated by the H3 bulb.
So in hopes of eliminating this problem and getting better lighting, I just dropped $180 on this
HID kit from Ebay: Normally I would not put a HID kit into a halogen housing because I refuse to blind other drivers. However this vendor has an H3 HID bulb available with the correct orientation so that it should preserve the excellent upper cutoff of these factory fogs.
The HIDs should run cooler. I hope that they will last longer, however that remains to be seen. The vendor I am purchasing from seems to have a good rep on various message boards, so I am hopeful that I will have good results. The HID bulbs are $90 a pair to replace, so I hope they will last years instead of months (or weeks) like the H3s.
