A better redundant system

A better redundant system
This harness offers two separate relays that give you some redundancy. I had to buy this to replace my old harness that only has one relay. The old system failed on my wife as she was on a trip 2 hrs from home. luckily she had working fog lights.

These were exactly what I needed. They allowed me to install almost all the HID wiring inside my lamp housings for a stealth install, they eliminated the need for Bulb Out Warning resistors, AND they allowed me to have high and low beam. Oh, and they are so simple a five year old could plug them in, and they work great!

Absolutely amazing, totally does away with the need for a traditional wiring harness for an aftermarket HID system. I think it took me about 10 minutes to plug it all in on my 2003 Escape, and I was good to go! Kit is solid, well manufactured, and professional quality. Fast shipping as well!

When i got this product it felt good in the hands but only realize very cheap h4 pins this issue can be work on to improve quality. What i needed it for it got the job done will just change the h4 pin to a stronger male plug. It will surely get the job done easy to install and recommended

update one this module burn up nearly damaging my switch this item maybe was just faulty wiring was properly done but item failed with less than a hour driving.

I installed this to get rid of the harness that goes across the whole front of the truck, installed over a year ago and it is working flawlessly with my HID light kit. 1999 Toyota Tacoma SR5 4WD 3.4l. I use H4 Hi/lo bulbs 35w, everything works fine!

5.0 out of 5 stars Plug and play solution
Reviewed in the United States on May 1, 2016
Verified Purchase
I installed a mini H1 projector with Innovited HIDs in my 98 Corolla and used this harness to connect to both the HIDs and the projector's high beam solenoid. Prior to buying this I was concerned about how I would do the wiring so that everything worked as designed, but this product made everything 100 times easier. Definitely a plug and play solution to something that could've been much more complicated. I recommend this to anyone who installs HIDs in a vehicle with stock H4 lights.

Update 4/2018: still going strong! I recently had to fix one wire going from the harness to the small connector for the brights but it was only a little loose so it wasn't a big problem. Still looking loving my lights and how simple this harness was to use!

Works fine.. if you plan to use as low beam only. If you turn on your high beams and back to low, the lights flick off and back on again. VERY BAD for the ballasts and bulbs. Guess this relay was too good to be true. Stick with a relay with a direct battery connection.

What an easy way to complete the wiring of the HID bulb kit. Although the kit wiring with a relay and such did not bother me, I really did not want to run these wires across the engine bay and complicate matters a little bit. The purchase of this kit made the install so much more easier. Literally plug and play. And off you go. Wiring seems well built, connectors are of good quality. Every car that gets an HID kit from now on will be accompanied by this kit.
