Abstract: A wayside signal (100) for a railway includes a plurality of light emitting diodes (21, 23) housed in a housing (31). The light emitting diodes (21, 23) output indication signals. Further, the light emitting diodes (21, 23) are configured on a first circuit board (17) which is thermally coupled to the housing (31). The housing (31) may also include heat sink fins (19) to dissipate heat generated by the light emitting diodes (21, 23) and associated driving circuitry (30) for driving the light emitting diodes (21, 23) also contained within the housing (31). An additional light emitting diode (25) may also be formed on a second circuit board (18) with the driving circuitry (30). The additional light emitting diode (25) provides an indication to anyone behind the wayside signal (100). The wayside signal (100) is further optimized for thermal efficiency and to be sealed against the elements. In regard to thermal efficiency, the first circuit board (17) may be metal clad and the housing (31) may be formed of black anodized aluminum. Also, a plastic insulator may be attached to the housing (31) and covered with a lamp base. The lamp base may be configured to be inserted into a conventional socket for a wayside signal (100), so that the wayside signal (100) of the present invention can be utilized with existing circuitry.
