No Smoking Fasten Seat Belt Replacement Lens

Affordable solutions to modernize Passenger Service Units

A simple retrofit solution for effective messaging on-board 737 and 757 aircraft.

Through a powerful combination of photoluminescent and LED technology, the new PSU (Passenger Service Unit) lens removes the need to backlight the No Smoking icon by moving it to a central position and illuminating the command with blue or green glowing photoluminescence, ensuring the sign is always visible even in low light and dark conditions.

The new patented PSU lens is a lighter, simpler, retrofit solution that can be customised to provide effective on-brand messaging to all passengers on-board.
