These flexible gooseneck lights are great for reading and can be aimed so that they don't bother the driver or other passengers.
These dome lights each have 2 bulbs and throw lots of light.They are inexpensive and mount easily to any flat surface.
How about that! A flourescent fixture that works on 12 volts! This excellent fixture uses a pair of conventional 4ft bulbs and is extremely low profile.
More of the double-bulb dome lights. In this truck, we hooked these lights up to a 3-way switch system (like the 3-way switches in your hallway at home). This way, the owner could turn the lights on or off from either cargo door, which allowed him to work out of the truck all day with the doors open, and only turn the light on when needed.
Recessed round dome light fixtures are sunk into the ceiling and throw lots of light. These lights are used in fire trucks and ambulances because of their durable, heavy construction.
