A warning device, such as a road hazard cone, comprises a supporting body 2 which has an opening 4 communicating with the hollow interior 2a of the supporting body. A lamp housing 6 located in the hollow interior has an upper part 8 removably secured to a lower part 7. The part 7 is secured in the hollow interior 2a by locking means 15 which are accessible and operable only when the upper part 8 of the lamp housing is detached from the lower part. This arrangement prevents the lamp housing in its assembled and operative state being easily removed from the supporting body, such removal only being made possible by means of a tool or key 21. <IMAGE> |
