Using this light bar is easy. You can either use it by itself or pair it with other lights. To enhance visibility, you can mount up to 4 driving 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 a simple bolt - on process, so you don't need any special tools. As for maintenance, since it has a textured black powder - coated finish, it's resistant to rust. But you should still keep it clean and dry. Avoid using abrasive cleaners that could damage the coating. And if you notice any loose bolts, just tighten them up to keep the light bar secure.
