Additionally you may want to check price and availability of replacement bulbs for the lamp you are considering. I had one like it once and the festoon bulb within is a special....hard to get on a wet winter night and expensive. Not your normal car type festoon bulb. I am not certain but you may want to check it out.
Thanks - I've already ordered them unfortunately... but I'll check out the bulbs when they arrive. It is mostly for compliance rather than because I actually need them - I don't intend to do any night time travelling and I don't expect that to change - nice sunny days are where my ribbing belongs
The info I got from the harbourmaster was:
"I quote below Rule 23 (Lights for Power-driven Vessels Underway), Section (c)(i) from the Prevention of Collisions Regulations:
a power-driven vessel of less than 12 metre in length may in lieu of the lights prescribed in paragraph (a) (which are masthead,stern and sidelights as required by a ship) of this Rule exhibit an all-round white light and sidelights.
There is a further Section (c) (iii) which might be helpful:
the masthead light or all-round white light on a power-driven vessel of less than 12 metres in length may be displaced from the fore and aft centreline of the vessel if centreline fitting is not practicable, provided that the sidlights are combined in one lantern which shall be carried on the fore and aft centreline of the vessel or located as nearly as practicable in the same fore and aft line as the masthead light or the all-round white light."
I'm honestly not sure whether the regs here are the same as UK, based on it, or completely different, but I think as long as I've got lights, I doubt anybody is going to squawk too much about exactly where they are. Hope not anyway
which is interesting - gotta go and read it now....
