contrary to what others have said about cheap materials and wires melting upon receiving the items i noticed the side that plugs into the headlamp itself is in fact a ceramic piece and its a perfect fir for my rig. it plugged right in fit perfectly and works great as for the people saying wiring is cheap and undersized it is not in fact it is larger than my o.e. wiring by at least two sizes and doesnt even get warm at all.

Upon first receiving this cable it looked very well made. The plastic was thicker than the oem ones. However, after a month I noticed my right headlight not turning on immediately but it would take 15 seconds. I opened the hood up and my surprise I saw the new connector partly melted already. I have the Sylvania SilverStar ULTRA TWIN Halogen Headlight installed.

4.0 out of 5 stars HALO H4 PLUG
Reviewed in the United States on February 4, 2012

Good quality. Had a problem in my Mercedes Benz w123 - 300D in that plug that connects to old plug makes it too tight for both connectors to fit in the recess. I cut off connectors and soldered wires. Works great so far.

Part of fit problem may be due to halogen boot on H4 lamps which sealed beams lack.

Buy the upgraded wiring harness for peace of mind! They increase the the wattage that can be handled from the use of some premium aftermarket bulbs...some of which are above the 55 watts of safe usage by the factory wiring harness (too high a wattage bulb can fry the factory wiring harness). They are easy to install (plug and play in seconds), and are an inexpensive upgrade that will protect your factory wiring harness.

1.0 out of 5 stars Deceptive looking wire
Reviewed in the United States on October 10, 2011

I am not sure I received the correct product, but what I did received was of very cheap quality. I say I don't know if I received the correct wiring because it was delivered in an unmarked plastic bag and not the retail package shown in the image of the wiring.

The wires seemed to be a heavy gauge due to the thick plastic insulation. However, when I cut the wires to use the connectors only, I found the wire gauge to be 20 gauge or higher with very few cooper wire strands inside the wire insulation. I would not run high wattage bulbs with these cheap connectors because your bulbs will burn up in a short period of time due to the very high resistance caused by light weight, high gauge wire hidden by the thick plastic insulation. I ended up throwing these in the trash and buying different light sockets of higher quality and true lower gauge wire.

Works OK. The connectors are a little loose inside the plastic housing. I also didn't like that the connection is unshielded from water. I cut a piece of a bike inner tube and stretched it over the plug before plugging it into the harness on the car. I then stretched it over the harness to give it some kind of weather shield. Manufacturer really should have some kind of rain shield on this. Something like the rubber boot on the back of the headlight housing,

3.0 out of 5 stars Should have gotten the pigtail
Reviewed in the United States on July 2, 2013

Should have gotten the pigtail version, but thought there might be a chance the plug would fit the oem Suzuki, but no, it's an extension. Fit the bulbs well enough that I had to order elsewhere because Amazon decided I couldn't get them here, and cancelled that part of my order for me. Got them cheaper on Ebay anyway.
