Customer Q&A
Ask a question to 1A Auto customers who purchased the product
do I need to replace the electrical connections in order to switch the xenon headlights to halogen lamps?
Jose F March 23, 2017
You would need to rewire the entire headlight wiring to switch xenon lamps to halogen lights. They use a different level of type of power.
Alex P March 23, 2017
Thank you for your help Alex.
Jose F March 24, 2017

Why wont this assembly work with my HID ballasts and bulbs??
Thomas B October 24, 2017
The cut outs on the backside where the bulbs are inserted are a separate size between composite halogen headlights and HID/Xenon headlights.
Alex P October 24, 2017
I pulled the headlight completely out and replaced the entire headlight with these. Works great!
