Abstract
A multi-flash strobe light pattern is superimposed on each individual light pulse produced by an incandescent lamp to provide a warning signal of enhanced visibility in a particulate laden ambient environment. The first pulse of each multi-flash strobe pattern is delayed for a time period, subsequent to energization of the incandescent lamp, which is equal to at least 80% of the time required for the incandescent lamp to achieve its maximum light output intensity.
