I recently tried to have a set installed on my car but to my dissapointment it couldnt be done as it was reverse polarity and needed a euro kit apparently.
For the rest of you out there i think its very worth while mod as it shouldnt be any more than 300 bucks installed.
If anyone can help me out with a 6000k H7 kit that WILL WORK on a 2006 astra il be forever gratefull
