Received these lights when the weather was sub zero and the heat in the garage was out. So I got to sit and look at these for a couple of weeks. Where else could I use them? They are almost the right size to hide under the bed rails of my truck, but just a little to wide. They would do a good job of lighting up your truck bed. I would use all six for that task.They would also be good lights to use in a truck bed cap. Just make sure to aim them so they are not shining in your eyes when you access the topper. I think they would also make good camp lights on an overlanding rig.They are well made and do not heat up with extended use. While mocking up the lights to determine where I wanted to mount them, I had them running for about an hour and they were only slightly warm. Also being LED's, there is no real power draw on the battery that I would be worried about. I would imagine that they could stay on overnight and you could still start your truck (as long as it has a good battery).They have a good finish on the aluminum body and there is plenty of length of the wire leads so you can to connect them to a wiring harness for power.Now that being said, if you look at the pictures I think that with a full size truck that I really need to have more lights to get the amount of light that I want to fully illuminate around the tires, front and back of the truck. Each of the rock lights puts out plenty of light, it is just the size of the truck that I have areas that I would like to be illuminated the the lights just cannot reach.My plan is to use two of the rock lights for each wheel and two evenly spaced under the cab. I also want at least one light in the front and back of the truck so a spotter can easily see any obstacles with out a separate light source.Now on to finding more lights!
