The Dome-TrioMobile Data Computer Light helps provide lighting to mobile data computes in the squad car. This directional LED keyboard/control light can be integrated with the factory dome light, which allows for easy installation and minimum failures. The Dome-Trio light system is manufactured from high-grade spun aluminum and employs a single high-intensity narrow beam LED and has an adjustable brightness control. The brightness control varies in adjustment from total darkness to 60 lumens (five times brighter than the standard dome light). Once the light brightness is adjusted, a separate rocker switch was added for the on/off feature to prevent having to repeat the brightness adjustment. The 10-degree beam of light makes a sharply defined spot about 15 inches in diameter at the keyboard. This controlled beam of light provides the best keyboard/control visibility without illuminating the interior of the vehicle.
