Original warning text

1. MARINERS ARE ADVISED THAT THE FOLLOWING HAZARDOUS CONDITIONS MAY
   EXIST WHEN OPERATING IN THE VICINITY OF THE STRAIT OF MALACCA:
   A. LOCAL PILOTING INSTRUCTIONS FOR THE STRAIT OF MALACCA INDICATE
      THAT AN ALL-ROUND RED LIGHT IS COMMONLY USED IN THE STRAIT
      OF MALACCA TO INDICATE HAZARDOUS CARGO. THIS LIGHT IS NOT
      INDICATED IN THE 72 COLREGS.
   B. DUE TO INCREASED PIRACY IN THE STRAIT OF MALACCA, VESSELS
      WITH LOW FREEBOARD MAY BE USING SECURITY LIGHTS UNDERWAY,
      WHICH MAY OBSCURE THE NAVIGATION LIGHTS OF THE VESSEL.
2. MARINERS ARE ADVISED THAT ALL TYPES OF HIGH INTENSITY LIGHTS WHEN
   USED AT SEA MUST BE PROPERLY DIRECTED OR ADEQUATELY SCREENED.
   IF THESE LIGHTS OBSCURE THE NAVIGATIONAL LIGHTS OF THE VESSEL
   OR INTERFERE WITH THE NIGHT VISION OR SAFE OPERATION OF OTHER
   VESSELS OPERATING IN THE VICINITY, THEY VIOLATE THE 72 COLREGS.
