ABSTRACT:
An improved structure of the automobile lamp includes a base, a fixing pipe having two longitudinal grooves, and a lamp seat fixedly connected on the base inside the fixing pipe for combining with an automobile lamp body. An outer pipe is provided with a driving gear at its bottom end for engaging with a DC reduction motor and two staggered threads at its inner call. A colored inner pipe is provided between the fixing pipe and the lamp seat. Two guiding rods extend from the inner pipe and penetrate through the two longitudinal grooves of the fixing pipe to be received in the staggered threads of the outer pipe. When the output shaft of the DC reduction motor rotates, it drives the outer pipe to rotate and move the inner pipe forwardly to cover the automobile lamp body to change its light into another color.
