Tornado A-frames/navigation lights
I've just spend the last few hours replacing my navigation lights and putting in new marine grade wiring for them. Not the most exciting job trying to thread cable through the A frame and make it exit a 5mm hole the other end.
Anyway, why do Tornado/Barnet Marine fit/sell such strange A-frames? Itís impossible to buy port and starboard lights that fit on a forward facing surface. Previously I had installed two port and starboard lights, but because they were mounted the wrong way round, forward facing not sideways facing, they light crossed over by 25 degrees at the front - highly confusing for other boaters.
So this time I had to buy two bi-colour lights and block out one colour on each. This was achieved by cutting up and old plastic folder and fixing it on the outside of the lens. Works perfectly and looks pretty good too.
