Lasizas Stern Light

[SteveIOW]

Have just purchased this low profile LED stern navigation light. Fitting instructions do not state the orientation, ie should the fixing screws be side by side or one above the other. Pretty sure only one way will give the required 135 degree horizontal beam.
Anyone know which way it should be fitted please?

I guess the fresnel lens should be vertical? Try powering it up?

Ours is vertical.

It’d have to be vertical to make the correct angle.
Check the manual thoroughly as many LED fittings start blinking after a couple of years to indicate end of life and required replacement. This is intentional.
