Turns an hour job into 5 minutes.

To wire everything up correctly, make it look pretty, and protect it from the elements would have taken some work. This kit accomplishes all three of those goals for under $40, which is a pretty good deal imo.

only complaint.. Fedex delayed my package from arriving. subi mods got the package out quick and installation was fairly easy with the hardest part being taking off the bumper. i can easily tell this product is top quality and will last with no problems!
