In case the competition will be broadcasted on Television the level of lighting has to be checked with the responsible person for TV production. Special arrangements have to be made as required individually.

4800.1.2 The floodlights must be so placed that the light does not alter the topography of the slope. The light must show the competitor the exact picture of the terrain and must not alter the depth perception and exactness.

4800.1.3 The lights shall not cast the competitor's shadow into the racing line and shall not blind the competitor by glare.

4800.1.4 Obstacles and buildings in the immediate vicinity of the course must be clearly lighted.

[edit] 4800.2 Lighting Inspection and Course Setting

The TD together with the Jury must check ahead of time that the lighting conforms to the rules. The organisers shall provide him with light meters having cosine correction.
