White - Red STROBE LIGHTS and Anti-Col Lights
Helicopter safety is paramount and if all helicopters were fitted with White and Red Strobe lights (white on when away from persons, ie. red on when in the vacinity of people) as the standard rather than the dismal red anti-col lights the see and be seen would be very much enhanced.
From investigation it would seem that there are 'Authorities' around the world which do not allow white strobe lights to be fitted at all.
Do you have white/red strobes fitted?
If not why not?
Or do you use your landing light to enhance being seen?
