There is nothing worse than having your lights stop working because of poor wiring connections. This kit eliminates that issue completely.

The harness is a little expensive, but is worth every penny compared to most other

light harnesses. The only difficulty is figuring out where to mount the switch & extending

the wiring from the switch into the engine compartment & to the lights. Other than that,

it's as easy as ABC for installation. The quality & performance is excellent. Great Value!
Awesome product
