Great value wiring harness to connect higher voltage H4 bulbs directly to battery. Included adapter do your set whether your car is ground switching or conventional configuration. Good build quality with high gauge wire. Works great!

I absolutely love LED technology. I also really like older vehicles especially the ones that are tried and true and have proven themselves as valuable. One of those being my 1992 Toyota pickup truck. I’ve had this truck for longer than some of my kids and its never disappointed me. It’s not the prettiest or most comfortable but it will get you there and back, no matter what. I decided some time ago to upgrade the lighting to LED, but I soon found out I was going to have to do a considerable amount of research and rewiring to make this happen, so I decided to leave the headlights alone. Well behold, I came across this awesome little wiring kit. This is a high quality harness that is plug and play and makes those LED headlights function as they should. The harness is very well designed and fabricated. And the price makes this an excellent value. So now I’ve got those brilliant white LEDs in one of my oldest vehicles. And I like it.

I have a pair of LED Projectors Lens (they are turned on by the low beam of your car, and the high beam only activates the solenoid motor that allows a full opening of the lens) which do not have a driver or canbus, only the 4 bare wires, when connected directly with an H4 adapter (see picture), they did not work, the light does not turn on, my car does not recognize them.By using this Relay Harness (which has the advantage that it makes the projector lens or any led bulb you install operate directly with the battery, avoiding overloading the car's electrical system, at least that's how I understand it) I was able to operate my Projector Lens, but only the low beam, the problem is that my car has H4 sockets, which when I turn on the high beam then the low beam is turned off, both work independently.So if your car uses H4 sockets, I guess you will have this same problem, there might be a solution to this either with an adapter or by finding a way to connect the low beam cable from the projector lens to both the low and high beam of the H4 socket of the car.Note: the high beam works only if you hold the high beam operator (in this way both the low and high beam are on, as when you want to indicate something to another driver), without letting it remain fixed which will cause the low beam to turn off immediately leaving you without light, I don't know if I made myself clear. My car is a Mitsubishi Mirage 00, just in case.

I purchased this for my Jeep XJ. The wires are so underbuilt that it would fry out the light switch. I read that purchasing a kit like this, with separate relays per light, would help with reducing the load and frying the light switch. It has been working great since I installed! Definitely a good upgrade even if you aren't upgrading to LED.

Ha.Ving the issue of not getting enough power to the headlights. This fixes all of that. Becoming straight off the battery through the relays. Getting a 100% of the power you need to run your lights. The wiring was more than long enough. Inequality is very good. It's a well made product very good value for the money. Functionally, it works perfect and it was an easy install. And it definitely made the lights much brighter. Getting a 100% of the power that is required. No more issues with lights highly recommend
