These little tabs are great for mounting rock lights to anything. The tabs can be bent or positioned to be used in a variety of locations. We have used body mounts and other factory locations. We have also used self tapping screws to attach these to strategic sheet metal. They are aluminum so they won't rust but can also be painted or powdercoated. This is for a set of 6. They can also be purchased individually

We have used these for the Rigid Industries rock lights, Procomp rock lights and other. The distance between holes is roughly 2"
