An overhead hazard warning for an elevated work platform comprises a light source configured to emit light in a downward direction. The light passes through a first optical lens assembly, a template, and a second optical lens assembly to produce a pattern below the elevated work platform. A heat sink is located above the light source to draw heat radiated by the light source upwards and away from the light source.
