Navigation Lights 20m
This category includes all navigation lights that are constructed especially for use on boats up to 20 metres long and they are bigger than the ones for boats up to 12 metres. The various groups of this category include all round lights or stern, side and masthead lights.

Use

As in the 12 metres category, sailing boats must use stern and sidelights when they have the sails open and when they are motor driven, they must use the masthead light too. Instead of using separate sidelights, sailboats can combine them into one bicolour light.

Instructions of Use

The navigation lights in this category can be mounted either vertically or horizontally (tricolour) in relation to the deck and they are connected to the central and auxiliary circuit. They are mounted on the surfaces with screws, while the case is clipped on the base. Navigation lights should not be put under any kind of strain. All lights should be positioned in such a place so as to conform to the regulations.

Maintenance

Regular and proper maintenance is essential if you want your navigation lights to operate properly and for a long time. Therefore, Lalizas suggests that on regular basis you: - Spray the lights with a silicone spray to protect the casing

- Check the nitrile water resistant seal and if necessary replace it

- Clean the contacts and spray them with a product that is only for electrical contacts

- Check the bulb and if necessary replace it

Replacement

All navigation lights must be replaced when the lenses change colour or you notice crack on the casing or the crystal.
