I will like to confirm that HID's do produce glare, but definitely close to none on halogen projectors. Many other customers have purchased these kits and there is close to no glare for oncoming traffic. As for reflector-based housings, glare can be SIGNIFICANTLY reduced if the beams are pointed slightly downwards of about 5 degrees. Still great visibility without glare :thumbup:. If you are worried about your stock harness, you can make your own wire harness + relay. This is just to insure your wiring safety. You can find these all over hidplanet.com. Purchasing them would be about $30-50, depending on which store you look at. Make one yourself, IMO it's funner and you get more out of it.
Any questions, let me know!
Peace!
