A novelty item that spins at least one array of lights to produce a predetermined changing pattern of lights. This polarizing effect is induced and controllable by the level of ambient light impinging on the device. Herein, an MPU replaces the optical lens in an optical axis direction, and a TE signal detection circuit or an RF signal detection circuit detects the TE signal or the RF signal at each of lens positions. The shock absorbable member is fixedly coupled between the steering shaft and the handlebars.
