This is a premium high temp ceramic H4 type headlight socket kit w/ terminals and a protective silicone rubber boot. This socket is a match for the connector terminals found on most high/low headlights including 7 inch round sealed beam headlamps (H6024), rectangular headlights (H6054, H4666, & H6545), and the halogen replacement lights available for most cars built before the 1980s.  This socket is also correct for quad headlight systems for the low beam (outer lamp), including 5 3/4 inch round headlights (H5006) and rectangular H4656 bulbs.  This socket is also great for high temp bulbs like xenon lights, HID, and other high output bulbs. This ceramic connector can easily withstand up to 300º C or 572º F, making it nearly indestructible!

This connector is commonly referred to as an H4, HB2, P43T, or 9003 type connector.  It is ideal for connecting to a factory installed wiring harness, fabricating extension harnesses, and other custom harness builds.  This connector is designed for 12V-16V applications. The terminals can accommodate 18-14ga wires with ease.  We also carry a stock appearing plastic version of this connector.  In addition, for those applications that require a little extra wire, we also offer this socket pre-wired with quality 14ga US made wiring pigtail.

This product is offered with the classic muscle car restorers and vehicle customizers in mind.  This socket kit is a great way to connect to existing head lamp wiring without splices or modifications. It is also a perfect product for custom made headlight harnesses and extensions. For those customizers looking for brighter headlight output, we offer a free download of our do it yourself Headlight Relay Harness in our tech section.

  1. H4 Headlight connectors 5 Star Review

    Easy to use and great quality. The best option by far.

  2. A Great Upgrade over factory plastic 5 Star Review

    I installed a pair of these on my 70 Mach I because the plastic factory ends was rotted. These crimped onto the old wires and made a solid connection. The black rubber covers hide the fact that they are ceramic. I would do this again to any car. Very good quality and a fair price.
