10000k bulbs have the least light of all the HID kits. The bigger the number, the less light and more purple.Jaysc said:Halo Led Projectors work better with HID Kit than with Halogen H1 Bulbs. I owned one set myself, and like the output of the light. These headlights are easy to install your self. I practically paid a body shop to get them installed with a 1000K HID Kit. I paid $150 for installation but did not even adjust them. So I had to get them off and calibrate them myself, so it took me up to 1 hour but happy with the product. I sugest that for those to purchase this type of headlights for a better light ourput, buy a set of HID Kit of 6000K or 8000K for better vision.
These also don't have the deflectors the stock headlights do so an HID kit would be very obnoxious and prone to tickets as it is illegal nationally to do this. The purple would make them magnets. I would either do the HID kit or this with silverstars, PIAA or similar bulbs and not HIDs unless you don't care about the couple hundred bucks for each ticket. They do look nice though.
