I've have the 90/100 setup for a long time now and no issues at all with any components including the bulbs. No bulb blow outs even though i flash most of the "high beam morons" the coming from the opposite direction , and like someone said it does bring most morons back to low beam. I had the same setup on my accent for 4 yrs without any issue. The guy who does mods on my car is very good and he uses good/original products as well. Also the beams are alligned so no blinding when on low beam, but high beam is a different story.
