BARRIER GATE ARM WITH RECESSED LIGHT HOUSING
A vehicle barrier gate arm is pivotable between an upward and downward position. The gate arm has an exterior wall and one or more recessed light housings within visor channels. Each light housing may contain a light system such as an LED light strip or a light rope. The light housing is positioned at the inward end of a visor channel. The visor channel is defined by two opposing, parallel visor channel walls extending inward from the exterior wall. Each visor channel wall has a retaining fin extending perpendicularly from the visor channel wall into the visor channel, thereby forming an aperture in the light housing. The light housing is situated behind the retaining fins. The retaining fins and the visor channel walls form crooks within the upper and lower corners of the visor channels. The visor channels and the crooks shade the light housing and create dark regions of the channels. The shaded visor channels provide a stronger contrast between illuminated and non-illuminated LED lights strips, allowing an observer to better determine whether the LED lights strips, which often act as signals, are activated or are not activated.
