Zenex HID Kit Single Beam Wire Relay Harness (H3)

Single beam harness is for TWO headlights . I ordered two of them as I am one whom has an issue with one light going out. cheap Chinese stuff or quality German Philips set up (which I like better btw, 35w over the overdriven 55w systems) one light wouldn't get the current after that initial "pop" on... so I wrapped the "other side from the battery" (long cord) up on each, wired em up directly from each headlight control/supply line and ran/extended the power line from the non battery side, and were good to go so far!!cables themselves are simple enough (as compared to the Morimoto Harness which has a double rely system, I took out) the connections into the "relay block" aren't very secure but once they are connected work like a charm!

Super cheap! ..but you really get what you pay for with this purchase. I've had to replace or repair every single connector including the relay. They are all super cheaply made and the pins loosen up over time in the plugs. It's perfect length and fits a full size truck really well, but beware it won't last forever and once you start reading repairs the price no longer seems worth it.

Works fine but really not the cleanest looking loom out there. I bought it to wire hid fogs to a dodge ram. The loom was only just long enough running the most direct way, not the neatest. Relay was cheap junk, replace when you install or expect a failure at some point.Only has one input plug from the power side of the light so if you have error lights, there probably going to show up.Plugs were all a good fit and quality.Power and neg wires from relay really quite short also.Overall it did the job but was a pain as there wasn't spare length to make the install as neat as the factory wiring like the ddm harnesses I used for my low and high beams.

I purchased this to fix the problem my 2015 Silverado had. It would turn on the lights then shortly after turn themselves off. I had 55 watt hid's and they would turn off because of the high current draw during ignition and warm up. This relay bypassed the original vehicles harness and got the power straight from the battery. This fixed the problem. The only other problem I have is since it uses the vehicles harness to sense when to turn the lights on, when the vehicle is on during the day, the relay triggers and turns the HIDs on because of the Day Time Running lights. The fix is it to remove the DRL fuse but this could be fixed on the actual relay harness by including a few diodes to provide a voltage drop without negativly affecting their product. This why I only gave it 4 stars.

Any time I do and HID kit again, I'm using the relay kit too. Its all plug and play. This time I didn't have to add any wire to the fused power wire.UPDATE. Everything is working fine. No problems with the relay kit. However ordering Zenex has been a pain in the you know what. I have done a review, I have given good seller feed back, but they keep sending me e mails to do a review and seller feed back. Its almost every week I get e mails from Zenex. Its almost like they are trying to make themselves to be the best. Get over it. Its only wires and a relay, I could of made it myself if I had the stock light connectors.

I thought it would solve my issue of HID's not always starting up, but i found it was the ballasts.It did help start up though, they get bright fast, and are more white than blue(55w Slim Ballast 9006 6000k bulb) like they had been bluer than i liked. It was very easy to install, i did have to extend the power wire, but that was only for aesthetics so i could route it differently and hide the whole set-up much easier.What you can see looks very good, loved the covering on the wires, and it was much thicker wire than i expected from something this cheap.If you are looking for a relay kit BUY THIS, it is more than worth the price,, and it looks very good.

Not only did these show up a day early, but the quality of these units are actually pretty amazing, everything is done ver professionally, and I couldn't be happier that all the connections fit the OEM connectors without modification. I would consider these well worth the price advertised, it would have taken me at least a day to source all the parts and assemble this myself. not to mention the price on components would have far surpassed the price I payed for them. Well worth it again!!

I bought this for my 2014 Silverado. It was too short to reach the driver side H.I.D. so I had to purchase two and splice them together. also the relay makes a loud buzzing sound that I can hear from inside the truck. One day After about a week of installation my truck wouldn't start,the battery needed to be jumped I think some how the relay drained my battery.i took it off haven't had a problem with the battery since.
