H4 Pigtail Socket Wiring Harness Headlight Plug Heavy Duty14AWG Ceramic Headlight Connector-H4 HB2 9003 (Pack of 2)

They are excellent plugs that are made of a high quality polymer shell, a very tight fitting rubber cap to weatherize the back of the plug while allowing the wires to come through, and a ceramic where the blades actually are. They are high quality wires, I was pleasantly surprised, and they do come prestripped. These will fit a 5.75 (5x4-3/4) sealed halogen beams found on your classic Chrysler and Mopar offerings, which was really just awesome in my book. Used them to replace the originals on my 1963, and frankly after years and multiple "repairs" it was time, and for basically no money. I cannot speak on the butt connectors as I crimped and soldered the wires together, but the blades they used look nice and hold a memory even after multiple removals.

It appears the 2 pack doesn't come with wire crimp connectors? Why only on the 4 pack? Otherwise they seem good enough to replace old melted headlight sockets. The wires are thick and copper on mine purchased in fall of 2025. They are also pre-stripped so you don't even need a wire stripping tool, just pull the sleeve off the end and push it into a crimp connector and crimp it down, and done! Make sure to use electrical grease in the sockets before connecting to the bulb. The copper wiring inside these is actually thicker than the wire in the OEM Toyota headlight wires. A 14-16ga wire crimp will work with these thicker wires.

I purchased these to get rid of the problematic Hid headlights on my 2009 prius and go to a standard halogen bulb or led option and they worked perfect . I never measured the wires but was atleast 6" long wires whice was perfect for my need and the conversion took about 1 hour total that included the install of the new headlight assemblies .

Seemed more heavy duty than the old one that was half melted and loose. Decent quality.

I only required one, but these are good replacements sockets for a dirt bike enduro headlight. There is plenty of pigtail and after I made them the right length, I soldered them into place and covered the three soldered wire connections in heat shrink. My original socket melted because of a crash/short. it also took out my regulator-rectifier at the same time, plus blew my taillamp and the headlight bulb. It was an extreme example of cyclical failure. After I finally figured out what was wrong, and replaced the lamp socket, I was able to diagnose the other failures and repair those.

Cheaper and just as good quality as the oem plugs. Fast shipping. Thanks!!!!

They worked perfectly and came with connectors

Good solid connector. Plenty of wire on the pigtail

Bought these for a friend's Mazda 3 and they worked perfectly, the wires were exactly the same as OEM.

Replaced the old burnt ones for my headlights and they work pretty good.

perfect for my car

Work well, but don’t plug-in all the way

I replaced one on my 2012 Honda Crv its working good. Its been 2 months so far
