Abstract
Signal lamp assembly comprising a light source surrounded by transparent lens walls in four horizontal directions is produced by molding the lens walls in two portions and securing them together. Lens patterns can be molded in three directions, but due to molding limitations, the fourth side cannot be easily molded into a lens configuration. In order to provide a lens for the fourth side, a separately made molded lens insert is placed in receiving and retaining grooves prior to the housing portions being secured together. The resultant assembly retains the insert in desired position and lens walls are thereby effectively provided in the four directions.
