I've had my HID low beams installed for about three weeks now. No issues whatsoever. Mine take about 3 seconds to warm up, but that is fairly normal with HIDs. The install is not too bad, but definitely take a look at max's thread about the install... it is a stick in the 'exterior & lighting' section. helps a ton.

my install took me about 2hours and that was only because it took me about 30minutes to get off the radiator reservoir...
hint: pull with teh angle of the grommet not against it haha

all in all i'm very pleased with them. they have great projection and are nice and white. i will take pictures of them sometime soon...i got the 6000k and they are pretty darn white...

so all in all, i'm happy.
