Review on H4 Headlight Relay Harness Kit for Toyota Pickup & Tacoma - Solve Dual Ground Problem by Matt Kucrud

After installation the wiring harness worked as advertised but a few nights ago I was driving home around 10pm and my headlights went out. I had to travel 5 miles to avoid danger as my only source of light. There aren't many street lights where I live. Upon inspection, I found that one of the connections the manufacturer is responsible for had loosened and loosened while driving. These are all labels with a tick. I recommend staying away from this product. Even without bad assembly, the wires are thinner than desired and too short.
