Before installation. The configuration is good.

Everything as described, just needs to be installed, looks good, comes with its PVC case and spare fuses.

Everything is fine.

Heavy Duty LED Light Bar Wiring Harness Kit

Perfect as always! This is the third one I've purchased. Excellent product.

Just install it yourself, there's no manual.

Heavy Duty LED Light Bar Wiring Harness Kit

Misleading, no light with only cable.

Looks good, long enough, with switch and fuse as well as relay for safe switching and power transmission.

Ok.

I am satisfied. It's a good product.

Excellent product, very good quality, comes with its relay and fuses, highly recommended, ready to install.

very well-made product

The connecting cable can be extended for use.

The performance-to-price ratio is good 👍

Everything is okay

Thank you….

Good well made product but dident read the description properly so i thought it came with the lights in the photos.

The switch is not the one I ordered.

Solid and high-quality cable. With the switch and the fuse, no further work is required to connect the lights.

It's the best, thebest

The button is an LED bar instead of two headlights.

Perfect.

It looks to be of good quality, I haven't installed it yet. It has several protections, which is always good. As for the cables, I was expecting them to be a bit thicker.

super good quality
