When is the optional Enhanced Lighting Controller needed?
The REDARC G52 series gauges are especially helpful in all light conditions, especially at night in instances when they need to be dimmed.
If your vehicle has dimmable dash lights with the dimmer in the negative or earth line of the dash lights, in most cases you can simply connect the gauge dimmer wire direct to the dash dimmer and the gauge brightness will follow the dash light brightness.
If your vehicle does not have an earth side dash dimmer, and you find the backlight too bright at night, REDARC recommend using the optional GA-ELC (Enhanced Lighting Controller). The GA ELC, triggered by the park lights, can be programmed to set the daytime brightness and night time brightness and even different colours for daytime and night time.
