The purchased here Bosch +90 are just gorgeous ...
for over 40.000km yet I almost always burn on board, both lamps still light ride. Illumination is very good, the selectivity in the border area is very clear (In addition, however, it gets dark very fast) coverage is in neat set searchlights same, but in the long-range noticeably brighter than the competitors. Light color is relatively bright, still in the rain (there more yellowish light colors would indeed points) still very good.
Why keep the lamps with me as long as I do not know, but probably because I only anschalte the spotlight after the engine starts (voltage spikes is the magic word for the ever annoy why blow your headlight bulbs as early ... to leave the headlights on and to use the automatic shutdown of the veh's mE has a much earlier death of pears result ..)
for me the Bosch +90 is the best H4 bulb which is currently on the market.
A few others I've already tried in the past ... (The Philips Premium, is a classic lamp with a little something more light, and almost eternal life quite recommendable, (new name is now Vision without additives in the name). The Osram Night Breaker were of the light output forth OK but a bit too quickly blown (comes with the newer version's a little bit better and are still in the car my wife installed)
