Okay, so some might consider this a bit ricey but....
Harbor Freight now sells HID foglights. $180 is really cheap for HID anything.
HID foglamps/driving lights
Anyway, for those in need of replacement fog lights, they might be excellent.
For headlights they might be useable though they might require modification. Felix has a pair of similar Hella lights in his Neo914-6 car. With only one pair of these you won't get hi/low beams. However at $180 a pair, it becomes almost affordable to have two pairs, one configured for high, the other configured for low beam.
I will probably try and modify a set of these at some point once I work down my list of projects to finish up. But if anyone else wants to try it out, they look like a promising alternative to the very expensive Hella units.
