Founded in 1972 Star Fabrication has a reputation for quality and durability and we manufacture everything right here in North America This triple 6" oval light box is popular with everyone from DIYers to transportation repair personnel. With our sealed, continuously welded, light box you can protect your lighting investment from snow, ice, moisture, and abrasion. Why don't we coat these boxes? The answer is simple. The mass market light boxes that are out there have very basic powder coat jobs which tend to fail very quickly. Furthermore if you're welding them on to your project any type of coating is in the way.
