A flexible transmitter light bar and a flexible receiver light bar may be used, in conjunction with a controller, to prevent or reverse closure of a door, such as an elevator door, when an object blocks the transmission of light from the transmitter light bar to the receiver light bar. By using flexible light bars, shipping costs, storage footprints and installation efforts are significantly reduced as compared to rigid light bars currently in use. The light bars may be applied with an adhesive and may further include one or more mounting holes. The light bars may be sealed to be water proof and permit easy cleaning thereof. The light bars may be useful in retrofit applications as well as in newly installed doors.
