Seeing as it takes 20 minutes to drive through the tunnel, it has been important to put several safety measures in place. Special lighting is installed to prevent drivers from falling asleep. The main tunnel light is white. But every 6 kilometres there are halls for stopping or turning, where the light is blue with yellow on the sides. This type of lightning will give the driver the illusion of driving through a sunrise and then entering daylight. Oglaend System supplied lighting support for these lights, which resulted in a total of 1650 lighting brackets.
