Abstract
A warning light includes a base to which an elongated post, formed by a plurality of tubular segments telescopically jointed, is fixed to support on the top end of the post a lamp unit.

Each of the legs is constituted by a primary member and a secondary member pivoted together with the primary member extending out of the respective hole of the base and the secondary member movably received within the hole. The hole is provided with an inclined inside surface which define an expanded lower opening on the underside of the base so as to allow the primary member to extend from the base in an inclined, diverging manner to define an enlarged bottom area for more stably supporting the warning light.
