2000 single cab silverado I recently bought some halo projectors off eBay aNd put them on my truck. They of course came with a halogen bulb but I upgraded to hid. I've had them in for a few weeks and they seem to set a real nice pattern and beam. But is there anything I should have done when putting HID into a Halogen projector housing for perhaps an even better light pattern? Is there any little steps I may have missed instead of just simply switching bulbs?
