- said signal light tube having a joint base toward an end of said tube;
- said base structure comprising a base board;
- said base board having a direction of extension;
- said base board carrying a pivot lug projecting therefrom and normal to the direction of extension;
- a first pivot shaft pivotally connecting said pivot lug and said joint base for enabling pivoting of said light tube about said first pivot shaft and about said joint base with said light tube swingable through a plane to selected angular positions with respect to said base board;
