PURPOSE: To obtain a lightweight, compact and portable light structure easy to handle by providing housings each storing an electric bulb on a bridge via ball bearings so that the attitude can be freely changed.

CONSTITUTION: A pair of ear hook arms 3 are provided openably and foldably on the right and left of a bridge 2, the arms 3 are provided openably and foldably on frames molded integrally with the bridge 2 via preset hinges, and batteries are stored at base sections. Electric bulbs 11 are replaceably screwed at end sections of the bridge 2, ball bearings 8 are integrally molded on the outside and extended forward, and cylindrically injection-molded housings 9 with lenses 12 are stereoscopically supported on the ball bearings 8 so that the attitude can be freely changed and adjusted. A light structure which is lightweight, compact and convenient to carry and has good operability and excellent durability is obtained.
