Lalizas 'Power 7' bicolour navigation light for small boat.
This is a vertically-mounted (e.g. on a pulpit).
Installation is simple: just fix the baseplate, connect up to your boat's 12v system and put the cover back on the light and twist it to lock.
The light includes a 12v 10W bulb, so it is ready-to-go. The bulb can be changed by the end-user if the vessel uses a 24v system, i.e. the 12v bulb can be replaced by a 24v bulb (not included).
