I won't dispute the components are cheaper than that of Bosch, I'd hope Bosch was using the highest grade parts possible for what they cost. What I'm disputing is why you guys have such a bug up your ass's about them when your reasons are just statements with no real information behind them. They provide more light than standard halogens, use less amps to maintain that light after the gas is ignited, they are about the same cost as Sylvania's higher end halogens, they make every road sign or road stripe glow like neon (thus visibility is clearer and safer). For every one person that says they are junk, there are hundreds of satisfied owners who have had no problems with theirs, like me for instance. It's cheap and it works.
