Review on πŸ”Œ 2pc H4 (9003/HB2) Headlight Socket Converter Kit for H4652, H4656, H4666, H6545 - Plug and Play Headlight Wiring Harness Connector Plug by Matt Ellis

Have to repeat these

I modified the headlights on my Blazer. Operate the headlights in battery mode and do without completely inadequate factory wiring. I ran 12 gauge wire to the control relays and 12 gauge wire from the relay to the headlight. Putting 18 gauge wire in this circuit makes no sense to me. The way these plugs and adapter cords are arranged should work for most people.

Pros
  • Great design
