attached to the side of a water craft or vessel along the entire perimeter to prevent damage to the hull the mounting face 40 in fig2 is attached to the face of the hull where the rub rail or rub rail insert is to be mounted replacing the standard rail two mounting lobes 12 at either ends of the mounting face 40 are designed to secure the rail to the hull helping to create a water proof seal ensuring the rail stays attached and to prevent water from damaging the light source 48 there is an access flap 22 forming the majority of the mounting face 40 and a formed gap 28 allowing an individual to pry said access flap 22 open and obtain access to the light source 48 after the light source as been accessed the flap 22 will fold back into position and the formed gap can be sealed with silicon creating a fully enclosed water proof light source housing 42 progressing outward from the internal light source housing 42 fig2 exhibits the primary components of the light altering rub rail in the version without the metal strip the three linear concave light refractors 26 will bend as much light as possible for even distribution the first linear concave light.
