Yes, they are worth it in my humble opinion. But I insist, you have to check them out, bargain and decide. In the previous GLi, I had already wasted a lot of bucks in going for the cheap Chinese HIDs without warranty, then they would flicker and I'd get another blaster, again they would malfunction and again I'd get a bulb or something. Finally when they started working okay, I had already spent around 12k.
But put the shopkeeper back in his shoes and get the right price. Brotherly advice, if you don't need the remote control option, get the same stuff for 6k with warranty
