Using this light bar is easy. You can either run it on its own or pair it with other lights. To enhance your visibility, you can mount up to 4 lights on it. Make sure the lights you choose are up to 6.5' in diameter and 0.5' in depth. When installing, it's just a simple bolt - on process. As for maintenance, since it has a textured black powder - coated finish, it's resistant to rust. But it's still a good idea to clean it regularly with a mild soap and water solution. Also, check the bolts periodically to ensure they're tight. Don't use abrasive cleaners as they might damage the finish.
