I bought one of those to try it and it blew straight away ,fair play i got in touch with the guy and sent pics of ,apparently there was a batch with faulty led's so he is sending a replacement .
If i were to buy another set i would go with the vision x lights ,they do a spot and a wide version ,borrowed a set last night for a night ride offroading and they were superb ,quality is much better than the chinese ones
