The little Windex
lights work great. You can buy the Windex brand name which mounts with your Windex.
The only disadvantage is the extra pair of wires to run up the mast. They just light up the Windex and are not very noticible otherwise.
Running with your steaming or
anchor light on is of course wrong and if I had someone in our race fleet who did it I was politely mention it once then protest if he/she continued.
I should add that occasionaly I have seen the steaming light put on to help wort out a problem on the fore deck but the helnsman should be aware that night vision will be affected and they have no rights.
