For sale is a NOS, new in the box, never used KC Hilites number 7602, which is a pair of 1/2-13 thread pitch light locks to secure your expensive lights from a two legged Rat. As you install your lights to your light bar or whatever you place the light in place, pass the wires through the locking nut and thread it onto the lower threaded portion of your light. Using the key portion of your lock set and a wrench tighten the lock  up sufficiently to keep the lights in place. You are now ready to complete the wiring portion of your install. This lock set works like the McGard style wheel locks, small alternating pins on the key correspond to holes in the lock. No mechanism to get corroded up like a traditional lock. There are many combinations of these pins so your set is unique, plus the nut has a rounded, hardened surface so a set of pliers or wrench can't get a grip.  These locks are in perfect condition and were "in the dry" in my speed shop in the seventies, eighties, nineties, and then into storage around 2005. If you have any questions about the compatibility of any of the parts I sell please feel free to contact me through Ebay, between the two of us we can figure it out.  Thanks for looking.
