I am a Catz distributor, so I guess they are coming from me! They really are cool and come with a relay to flip the lights up. These HID's only draw 35 Watts of power not enough for the computer to recognize the lights have been turned on.
Plastic housing is fine, they only run on 35 Watts so they actually run cooler than Halogens. The Galaxy Whites retail for $768 they are Purple in color. The Rising White (4300 Kelvin) are bright pure white and cost $568 retail and the Aqua White (5100 Kelvin) which I have, have a blueish tint to them and retail for $668. They are all DOT approved. I also carry non DOT approved HID conversions for $535 and $735 thier color temps are 4000 Kelvin and 6000 Kelvin respectively.
We can do GP pricing on 5-10 sets. GP pricing is 10-15% off our retail prices.
