Warning light with optical stage fixed on base

摘要

The lamp has a casing for a power source with an upper part (3), which has a hole (6) in one of its side walls. A bolt (7) can be inserted into the hole, and has a head (8) which rests against the side wall. The bolt engages in a fast locking device (10), and can be released from it by turning it about its longitudinal axis through less than 360 degrees. Alternatively, the lamp may be arranged, with the locking bolt through its base part, such that it also passes through a hole in the power source.
