Purchased spyder halo projector headlights for my 2001 chevy silverado. Purchased better quality low and high beam replacement bulbs(philips crystal vision ultra). High beams simply fit where plug and play, but the low beam projector is another story. There is a rubber boot over the projector and don't know if I can remove it without breaking something. The rubber boot has the plug that will work for pickup power source but what is underneath and will the philips high beam bulb even work? Thanks in advance for ANY input!
