Brought head headlights for my 2015 chevy impala. it took a few weeks for me and my mechanic to get a weekend that workout for both of us so he could install the headlight system. Turned out he informed me the headlight system appeared to be used and when he tested it before installing the headlights did not work.
Contacted customer service for XenonPro, (you have to communicate with them e-mail only) which l think is add. Well, it has been more than 30 days so no refund.
