2-Headlight H4 Headlamp Light Bulb Ceramic Socket Plug

I drive a 2001 XJ and had the usual headlight issues. After researching I decided on an H4 upgrade. It seemed like the only offering for an upgraded harness was the Putco, but after talking to people who bought the harness I realized I'd be better off building my own. I wanted ceramic connectors and after a quick search found this. I decided to go with it because of time constraints and figured I could modify the harness if I needed to.It arrived on time. The harness itself is sturdy, the connections are solid, and very well built. I mounted the relays on a panel just behind the battery. All the wires have plenty of length and it has an inline fuse. The relays are sealed well and look nice when mounted. I suggest using electric grease on the bulbs for easy install. With the ceramic inserts it's tricky getting the bulbs all the way in without it.

This is exactly what I needed for my 1991 Toyota MR2 Turbo's low/high beam LED headlights to function properly. If you are only able to get low beams and not high beams to function, or vice versa, this harness is what you need. I was given this product as a gift from seller SPL LIGHT in order for the headlights I bought from their store to be fully operational. Please check out their store! Unbelievable customer service! Thank you All Star Truck Parts, and special thanks to SPL LIGHT for the much-needed harness!!The headlights I purchased from SPL LIGHT:SPL 105W Brightest 5''x7''/7''x'6'' Projector Cree Led Headlights with DRL for Jeep Wrangler YJ Cherokee XJ H6054 H5054 H6054LL 69822 6052 6053 Toyota Pickup(Black Pair)https://www.amazon.com/SPL-Brightest-Projector-Headlights-Wrangler/dp/B073QR6BVC/ref=sr_1_4?crid=RWO3NKLDKRA5&keywords=7x8+led+headlights&qid=1560762230&s=gateway&sprefix=7x8+led+%2Caps%2C184&sr=8-4

Easy install. Works great. Didn't realize the relays weren't waterproof until it was too late. Careful where you mount them..

Installed on a 1991 Jeep Cherokee that was having some light problems. This kit fixed the problem of LED lights being "on" when the vehicle was started, and address the parasitic drain that was slowly draining my battery. I do not have a light meter, but I suspect it made my lights even brighter due to the age of my old wiring and the number of splices I found when installing this kit.The package contained everything needed to complete the install, but I upgraded the mounting screws to bolts using rivet nuts.Overall, completely satisfied with this item and will be purchasing another to install on my other old Jeep.

Needed the harness to get the high beams to work new LED headlights (B07BWBRDJ5). Good instructions with the package and there's also a good youtube video on the install. Simply plug and play to the stock harness. This harness attaches to the positive end of the battery and each light has a ground. Basically only uses the stock harness as a switch. Low and High beams now work. Harness looks to be of good quality. Install was about half and hour. Very happy with this.

Ordered this for an LED headlight install on my 2007 Wrangler; could not get LED retrofits to work.This is a decently made harness although the driver's side leg (longest leg) of the harness stopped working within a few minutes of installing. Internal connection at relay? Did not try to troubleshoot.DOES NOT ELIMINATE "FLICKER" (as stated in description) on my year/model vehicle. There are no capacitors or resistors in the harness, so the source of the 'trigger circuit' to the relays will still have to be addressed, as evidenced by the relays "chattering". I tried adding an anti-flicker module between the vehicle and the harness; this stopped the chattering, but did not resolve the issue I was having with LED lights on a 2007 Wrangler.Ended up adding an H13 adapter with 2x resistors to the vehicle and then the LEDs worked fine.

I used this on my '62 Chevy Biscayne. Worked perfect. Get the high current out of the headlight switch. I used splitters and now have 4 low beam headlights. Works perfect.

I am using this harness with my 1997 Toyota Tacoma as the headlight was upgraded to a higher wattage. Fits great and good quality.
