FIXED FOUR-WAY SIGNALS In the New Millennium |
Midvale, OH |
Modern Optics |
A number of older fixed four-way signals have been retrofitted with modern energy saving LED optics. While to a signal purist LEDs are somewhat foreign looking in a classic signal, they are a means to keep old signals in service, meet modern demands, and are relatively maintenance free. |

4-ways are not immune to adaptations to either conform with the standard that arrow indications are supposed to be 12 inch or to increase the effectiveness of a single stop indication in an area with a great deal of background light. Here is an example. |
This one is a DT cluster, but it shows an ingenious way to tag on a protected left turn indication. |
In some locations the yellow indications were equipped with tunnel visors on signals that otherwise had cutaway visors. The usual rationale for this configuration was to limit "side splash" of the yellow light into nearby bedroom windows. |
