Abstract

Abstract A warning lamp device comprising a base having two U-shaped stands pivotably secured thereto at the bottom, a telescopic support fastened in the base at the top through a socket joint, and a warning lamp attached to the telescopic support at the top through a socket joint. The two U-shaped stands are arranged into a cross structure to firmly support the device in place against wind force and the telescopic support is extended out to heighten the position of the warning lamp. The telescopic support and the base are collapsed to reduce space occupation when not in use.
