Any place that sells semi-truck accessories will have them. Grote and Truck-Lite both make a nice light. I have never checked at a regular auto-parts store for this type of light, but I would bet that they can order them. Your best bet is still a truck parts place. When I was designing semi-truck trailers, we used both the Grote and the Truck-Lite products and both are well built. If you get a set, get the security rings to hold them in. They are a real popular item to steal in some places, and if they are only held in by the rubber grommet, they are really easy to pop out. You can lose a hundred dollars worth of lights in short order. I just thought of something, most semi's are 24V, so your lights may not be quite as bright on a 12V system. I think you can specify whether they are 24 or 12 volt, but not sure. I never used the lights in a 12 volt application.
