signals in 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.

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.
Shown without wires for clarity.
Wires would come from the bottom
of the module and be connected to
the AREMA terminal block.
