I just added a HID kit to my Moss Lo-Pros and all I can say is WOW!!!!
It's like daylight. All the other headlights on the road look yellow in comparison.
BTW, The Moss kit has a proper cut off so I'm not blinding people.
I just got a H9 kit from this guy on eBay.
The quality seemed to be very good but likely a Chinese knock-off. For $75 vs. $300+ for the name brand kits I decided to take a shot. The install was straight forward and easy. We'll see how well it lasts but if a bulb or ballast goes out, I can now just replace that part.
