The photocell system features a photocell element which is formed inside a translucent tube. the translucent tube acts as a light diffuser. The photocell then detects the light which is diffused through the translucent tube. As a further feature of the present invention, a vehicle operator can control whether the vehicle headlights should remain on for a predetermined period of time after the vehicle is turned off.
