DOT means the US Department of Transportation, with the purpose of ensuring America has the safest, most efficient and modern transportation system in the world.

All types of trailers, from boat trailers, campers and horse trailers to 18-wheeler rigs, and everything in between, must have proper lighting before heading out on the road. As the United States Department of Transportation’s National Highway Traffic Safety Administration has strict requirements for trailer lights, check the trailer’s lighting system to ensure everything complies with federal laws before heading out on the open road which means all the trailer lighting exporting to North America must have it.

We are one of the biggest trailer light factories in China who has DOT testing lab and each light has to be tested and approval by DOT standard before package and shipment.
