Low energy usage lighting device

A method for forming a safety light, comprising:

• providing an OLED disposed over and in electrical communication with a circuit board;
• and
• securing, with a conductive adhesive, the OLED to the circuit board,
• wherein the OLED comprises:
• a cathode,
• an anode, and
• a light emitting layer disposed between the cathode and the anode,
• wherein the circuit board comprises:
• a supporting substrate,
• a first conductor track disposed over a first surface of the supporting substrate, and
• a second conductor track disposed over a second surface of the supporting substrate,
• wherein the conductive adhesive comprises:
• at least one carbon nanotube, and
• at least one adhesive matrix, and
• wherein the electrical communication comprises:
• the cathode in electrical communication with a first terminal of the first conductor track, and
• the anode in electrical communication with a second terminal of the first conductor track.
