LED Rock Lights can be used on any car, truck, or boat. These LED rock lights are Bluetooth controlled from your smartphone. The app is free to download and free to use. 4 pc and 8 pc LED rock light packages are available. Rock lights are fully water resistant so you don't have to worry about mounting them under a vehicle or on a boat where they will be exposed to water. However, the BT control box should be mounted inside the vehicle not underneath it.
