Have pretty much tried all offered Halogen headlamps, both in H7 and H4 in, but this is really the best to date. In the H4 version it is even a bit better than the H7, especially the high beam is very good at the H4 since been dispensed with unnecessary coloring of the glass bulb. Life seems to be better than you previously knew of high power lamps. I'll have these bulbs still in reserve.
