Interior vehicle lighting helps with passenger safety, task lighting, and added emergency lighting. Dome lights mount inside the domed space of a ceiling to provide general lighting inside the vehicle. Courtesy and utility lights help with visibility and safety. Dash and deck lights shine out the windshield or back window of working vehicles. Emergency vehicle interior lights are intended for police cruisers and other emergency service vehicles to provide additional lighting out the windshield or back window to alert other motorists and pedestrians of their presence.
