Marl's LED Gauge Rings provide a superior backlight solution for Rolling Stock, Speedometers, Pressure Gauges and Brake Gauges. More traditional light sources, such as filament bulbs, are prone to vibration and shock from the train's movement. This often causes irreparable damage and results in costly and unscheduled maintenance. Contrastingly, Marl's LED Gauge Ring units are fully potted ensuring extremely high resistance to shock and vibration, ideally suiting them to rolling stock applications.

The extended lifetime of an LED as compared to a filament bulb also helps train operators cut down on waste products and maintenance. In addition, LEDs also use less power and generate less heat than filament bulbs, making them a safe and economical option.

Marl's LED Gauge Rings are designed to be placed behind a panel and are secured using a bracket mounted on the Gauge. The Gauge Ring; product family comes with inbuilt protection against electrical transients, plus diode protection to guard against reverse polarity connection making this unit ultra reliable. The use of high intensity white LEDs gives excellent information definition and driver feedback has welcomed the use of LED illumination in locomotive cabs.
