Outstanding Delta-Tech brand is a modern, powerful wonder!

Convert your standard low-power headlights over to the ultra-bright halogen or Xenon headlights used in all the high-end European luxury cars. Besides the powerful bulbs, the other reason these conversions provide so much light is the use of a lead crystal lens and a specially-finished parabolic reflector. The Delta Tech headlight conversions are an easy bolt-in for more light and improved safety. Delta Tech also offers a DRL (Daytime Running Lights) conversion for increased safety on 7" round headlights for your classic. It's an easy conversion and requires only minor modifications.

Notes

  • Hi = high beam, hi-lo = high and low beam.
  • When converting to a DRL (Daytime Running Lights) system, you have to drill a 1" hole in the headlight mounting bucket. When converting to a 5-3/4" diameter system, you may have to drill a 2" diameter hole in the core support for lamp clearance, due to the 1" deeper lamp.
