Betalight B.V. is the leading supplier of Gaseous Tritium Light Sources (GTLS), also known as “Betalights” or Gaseous Tritium Light Devices (GTLD).

Betalight technology was developed originally by the British MOD for applications in aviation. Original designs included helicopter rotor-tip markers, directional markers, exit signage and in-flight refuelling markers. These applications demonstrate the tough, durable nature of GTLS light sources, being deployed in extremely adverse environmental conditions yet delivering stable, specified performance over 15 years without the need of any kind of electricity. Recognising the benefits to manufacturers and users, the technology was utilised for over 600 NATO stock numbers and more MOD applications for use in the air, at sea and on land. Today, GTLS are still used in many military sighting and applications including pistol sights, military watches and compasses.
