How do roadwork lights flash in sequence?

Answer:

Lamps are turned on via concealed ON/OFF button on front face. The lamps communicate with intelligent wireless technology allowing units to be laid out in a staggered taper in any order and will automatically synchronize to produce the visual impression of a single light source travelling front to back along the taper.

Hi intensity LED lamp that automatically synchronises a flash pattern, no matter what order, through a steady back light. Includes cone lamp bracket.
