I wonder if the two dock line guides I have up very near the bow replaced the original lights... I haven't used them yet, they are so far forward the way we tie off our lines go straight to the cleats that are much easier to reach.
For now, it's much easier, and even cheaper, to stock spare AAAs than to run wires and new lights.
My 303 did come with a big anchor light at the mast top, it even works too.
