Abstract
A warning light assembly for use on ladders having a plurality of rungs to indicate the presence of someone on the ladder. The warning light assembly has a switch activated by a person's foot placed on one of the lower rungs of the ladder. When first activated, the switch turns on a flashing light positioned about eye level. As the person disembarks from the ladder, his foot on the lower rung again activates the switch turning off the flashing light.
