Find the lights, collect the treasure and bring it to a central point.

There are meeting points marked with 2 different coloured lights (red and green or a blinking light).
Each colour belongs to a team.
2 teams row around and go to a meeting point with their own colour. There they find some treasure. Bring the treasure to a central point and look around for another meeting point.
The winner is the team with the most treasure. For them, there will be a “firework display” using lights in their colour.

Make a treasure map with a mark showing where to find the treasure.
