Review on 🔌 Optimized for SEO: iJDMTOY H4 9003 High-Quality Ceramic Wiring Harness Sockets for Headlights or Fog Lights by George Cochran

Great value extension if you are upgrading to H4 lenses and bulbs with Rally Lights or Putco wiring harness; gives you an extra 4-5 inches to get to the driver's light position without tying the wire harness to the radiator and oil cooler. I recommend them with ceramic terminals for possible heat transfer to the wiring harness when using 55/60w bulbs. . I melted a harness with Rampage lenses and European Osram H4 specs at 80/100w. You can fight the heat. At least on my 95 XJ.
