🔌 O-NEX HID Relay Harness H4 (9003 HB2): High-Quality Bi-Xenon Hi/Lo H/L Wiring Controller Review

Great product. Installed on my Jeep Wrangler burnt relay. I've been using it for a few months now, it works fine. I severed the connection cables and did a semi-professional rewiring. It works well as far as low and high light.

Power Cord Less Than 16 Gauge. Keep in mind that this is a very cheap cable kit. I had to replace a faulty relay from another kit that was preventing my high beams from working. It worked fine for that, right clicked.

Needed for my 2005 Scion xB that uses 9003/H4 headlights. I retrofitted it with bi-xenon projectors and wished for a high beam. It was easy to hook up, good quality connections and a decent built in fuse. Overall I would recommend this product to anyone looking to use bi-xenon in their single headlight bulb.

Did the job my old one burned out. Now it looks like a bunch of jumbled wires, but if you don't know how to tie the heads I wouldn't recommend it, but once you know the basics it's a pretty easy task, the only downside I've found , is that if you have a truck like me, minus the candlelight, have to take longer to get to the ground to work

Working well and pretty well designed. The only issue that bothers me is the main power cord. It has a 30 amp fuse and 16 gauge wire. I increased the size of the main power cord to 12 gauge, which should handle 25 amps of continuous current. I suggest keeping an eye on the main power cable when using the kit as is. Especially with the higher flush amp setup.

I used it as part of a HID system to upgrade the projector. The standard bulbs were 9007 and this harness was just plug and play. Anytime I upgrade my headlights to something better than stock I recommend using a relay harness like this to ensure the bulbs are getting the correct voltage. I like this kit because it has a built in high beam actuator with the correct connector to connect to the solenoid on the projectors I use. I would buy this yarn again.
