2Pcs H4 9003 HB2 Heavy Duty Ceramic Wiring Harness Sockets Male & Female Connector for Headlights or Fog Lights

Worked great. Used to install LEDs in a jeep.

I needed some high quality H-11 connectors to add Lightbars to my Tractor. These were perfect and fit the tractor pigtails perfectly. Very impressed with these.

Look good, wire gauge looks better than others that I had to return. Probably 14g which is fine for the LED headlights I run on motorcycles.

The metal parts of the connectors don't scream "rock solid" or "OEM quality," but they're cheap, work perfectly fine, are made of real ceramic, and hold onto sockets decently in an engine bay. Wires are a bit stiff though, but they even come with wire conduit. Great for the price, but not as solid as OEM harnesses.

very fast delivery great job Amazon thanks

Gotta say, this gets old after awhile... order a part on Amazon & discover that it's not made correctly. I'd pay extra money if the seller would just test & correctly represent that the part works before selling it - rather than leave that effort up to the buyer after the sale.The H13 male connector on this H4 to H13 adapter won't mate/click to a standard H13 female connector - just shoddy design work on the part of the supplier. This application was for 2007 - 2018 Jeep Wrangler JK.

Used on my 05 Dodge Ram 1500, previous wiring wore out and this wiring harness was easy to mount and worked great!

I have a 07' KLR650 and wanted to add fog lights to my low beam and an off-road bar to my high beam without chopping upmy factory wiring harness which had absolutely no extra length to lose.I splashed in the fog lights and off-road lights to their respective wires on these adapters and it was basically plug and play.If either The fog lights are off road light bar gets damaged or shorts I can simply reach in my fairing and unplug one of the adapters and the rest of my lighting will function perfectly.They seem to be really well made and fit a little snugger then the factory plug going to the headlight.I'm using all LEDs so it doesn't matter to me but the wiring on the adapters same as better than my factory wiring which was perfectly fine running die and low beam at the same time for almost 15 years 130 watt bulbs.They don't seem particularly waterproof so I packed some silicone grease in the back of the plugs that might be something to watch out for if you're putting these on a motorcycle or car with pop-up headlights.
