Review on 50-Pack Amber Mini Round Side Marker Lights With 3 LED Bulbs For Trucks, Boats, RVs, And Buses - Universal Waterproof Sealed Design, 12V DC Compatible by Alex Barnes

I used these lights to make well lights for my driveway. I had one burning for 8 hours a night for a month before I did them all. I used 46 lights with 4 in reserve. Every one of the 46 worked, I have found no bad lights in this batch at all. These lights are completely waterproof, they get doused with water ever night by my sprinklers. How long they will last is unknown but so far so good. Oddly, I had a armadillo digging up these well lights and gnawing the cans apart. This happened to 4 of the installed lights. Armadillos can sense turned ground and look for easy digging so the bugger was digging them up lol. I solved that problem by running my 1 ton truck over the brick the well light is set in and dousing it with cayenne pepper which they hate. Anyway, despite tearing the well enclosure apart and tearing the light out of it, the lights still worked! I'd say they are pretty durable. Also I am running these on 12VAC not DC. On long runs of lights (this is about 300ft of driveway) DC has a lot of loss and it also degrades the wire faster than AC power. The system was set up to run incandescent bulbs, these draw so little power that it probably wouldn't matter but I have a VAC transformer so thats what I used. And it worked. I can confirm they run fine on 12VAC. Most will never use the lights for this purpose but if you do, it should work just fine. Will they last? I cant say but so far they have. If they burn out I wont be returning them since this is not their intended purpose but 8 hours a night for now 2 months on one of the lights is a lot of run time in a car, so I would guess they should last in a vehicle application. Of course you have shock where as a ground mounted light doesnt. At least from my experience these are very well made lights.
