APPLICATION
The 891 Series LED Wayside Signal Lamp Modules were developed by Dialight specifically for retrofit applications where
replacement of existing incandescent light bulbs is desired. This installation approach provides all the benefits of LEDs without the
complex retrofit of the entire lens and housing assemblies. Installation is nearly as simple as replacement of the incandescent bulb.
Dialight lamp modules have been fully qualified for the Rail environment and incorporate power factor correction and total harmonic
distortion reduction circuitry.
Mechanical Dimensions in
inches and (millimeters)
Dialight is the recognized leader in LED
applications for Transportation Signaling, and
has worked cooperatively with leading Transit
Rail customers to develop this unique solution
to Wayside Signal applications for LEDs. It is
proven to be a preferred product over traditional
5mm LED distributed array solutions.
AREMA TERMINAL BLOCK
Shown without wires for clarity.
Wires would come from the bottom
of the module and be connected to
the AREMA terminal block.
