Does the 8pc Rock Crawl LED Light Kit include mounting hardware and something to hold the lights in place?

Yes, this kit includes 20 Zip Ties, 10 Zip Tie Mounts, and double-sided tape on each light pod for a better hold. The pods also have screw holes on each side and can be mounted with self-tapping screws when the application allows. If using the included double-sided tape we recommend the use of Adhesive Promoter allowing the double-sided tape to have the best bond.
