perfectly legal, really nice bright light from them, i have two in my car just now and find it a really good light to drive in. just a standard replacement - stirling branch has them buy one get one free at the moment!
so they last longer than hallogens??
whats the average bulb life??
do they have a filament? :-/ if they do then they are not HID are they but just xenon with a filament? ok confused now...
how much do they fit them from? Id rather do it myself...
Just remember and dont touch the glass when fitting it or you will dramatically reduce the bulb life - could even blow straight away as it creates a hot spot on the bulb from the oils from your fingers!
