A battery-powered lamp, such as a traffic hazard warning lamp has a casing formed with ledges for location of the bottom edges of the batteries to retain the batteries in the casing. A fixing bolt, extends through the casing and prevents disengagement of the batteries from the ledges. The casing has apertures, in two opposite side walls, accommodating a respective lens which is a tight friction fit and may have ratchet-like teeth engaging with the material of the casing to retain the lens in position. The switch is in the form of a terminal strip engaged by terminals of the batteries. The strip is longitudinally slidable and has a bridging portion which is in or out of register with a stationary contact according to the position of the strip. |
