Open any door and four ultra bright white LEDs light the surface of the automatically deployed PowerStep. These rugged lights are strategically placed for broad coverage of the step surface for maximum visibility and are reliable in the most extreme conditions. For your safety, the lights will stay lit for a full five minutes when the door is left open, allowing plenty of time for entry or exit. Close the door and the lights go out automatically as the PowerStep retracts.
