Hi,
I have ordered the exact same set of headlights. As I am from New Zealand, I sent the eBay auction to my mercedes mechanic (He works at mercedes and has always fixed my car)
He said that they look and sound fine and should work perfectly!
As the HID kit is under a one year warranty, any troubles have to be replaced by the seller
I know people on this forum believe ebay is selling cheap headlights and you should avoid them and buy OEM instead...butr for me OEM costs 700 US, which is alot for a 16 year old to spend on headlights
I think 300 US is a reasonable price, just my $0.02.
