HMI Light System

The HMI LED LIGHT SYSTEM is a 24VDC and 120VDC powered LED (light emitting diode) lighting strip with adjustable brightness. The system comprises a LED array that is supplied in a machined black anodised aluminium enclosure? a lighting controller supplied in a black powder coated alloy enclosure and a five position K&N for brightness control. The system is intended for railway rolling stock applications.
