Like most fulfillment centers, you’ll likely experience some delays in shipping, as our Warehouse team is running at reduced capacity.

Available with either halogen or Xenon bulbs

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 four-coated finish parabolic reflector. The Delta Tech headlight conversions are an easy bolt-in for more light and improved safety. Delta Tech also offers Daytime Running Light (DRL) conversions for increased safety on 7" round headlights for your classic. It's an easy adaption and requires only minor modifications.


  • NOTE: X=Halogen, Hi=High beam, Hi-Lo=High and Low Beam. Each is shipped with the bulb. When converting to a DRL (Daytime Running Lights) system, you have to drill a 1" hole in the headlight mounting bucket. When converting the 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.
WARNING: This product can expose you to chemicals including lead, sulfur, nickel, chromium, vanadium, titanium, polyvinyl chloride, and 4,4’-methylenebis (2-chloroaniline), which are known to the State of California to cause cancer and birth defects or other reproductive harm.
