These are navigational markers are found and seen along the Rejang river, especially along the Tanjong Manis- Sarikei route.
As seen from certain angle, the markers look like these. These markers are also equipted with navigational lights which are powered by solar panels.
The perimeter surrounding these markers are regularly cleared and prevents the outgrowth from obstructing the view.
To me,these navigational markers are still a mistery. What are the meaning of these signs? Can some one help me out?
