Installed the All Star Truck Parts wiring harness in my 2010 truck, and it’s been fantastic. The H4 headlamp compatibility is perfect, and my lights are super bright now. No complaints from me!

Decent but delivery took too long
The headlight relay wiring harness is decent quality, but the shipping took longer than I expected. The installation was straightforward once it arrived. The ceramic sockets are a nice touch, just wish it didn’t take forever to get here.

Not what I expected
I ordered this set thinking I’d get plug-and-play ease, but I ran into some issues with compatibility on my older truck model. The ceramic sockets seem good, but I had to modify some wiring. Definitely not effortless.

Excellent upgrade for my truck
I bought this All Star Truck Parts headlight relay wiring harness to replace the old, worn-out wiring in my pickup. The ceramic socket plugs feel really durable, and the H4 setup makes installation straightforward. Now, my headlights are way brighter!

Good quality but tricky installation
This wiring harness from All Star Truck Parts is solid, but I found the instructions a bit vague. After some trial and error, I got it working, and my headlights are shining bright now. Just be patient when installing!
