Aircraft landing lights are key to takeoff and landing, and should always be working and checked prior to takeoff. Replacement lights can be purchased from Amglo and XEVision.

At take-off, inside an aircraft, having all lights off allows the passengers eyes to adjust to the actual level of light onboard. Should an emergency occur theoretically passengers and crew reactions should be faster.

No, they are just amazing lights in the sky. The lights are produced the same way the colors in a neon tube are displayed. There is no danger to your health.
I believe the navigation lighting requirement is that they have to be displayed between sunset and sunrise, and during periods of limited visibility such as fog, rain, or haze.
Sure! You've got your taxi lights to use as headlights, so you can see the edges of the runway and not run off the sides or end of it. I wouldn't recommend landing on an unlit runway, though.

A sailboat under sail that is 21 feet in length must display a combination of navigation lights, which typically include a white stern light and a red and green sidelights. The red light should be displayed on the port side (left) and the green light on the starboard side (right). If the sailboat is not under power, it is not required to display a masthead light, but the sidelights and stern light must be visible. These lights ensure visibility to other vessels during nighttime or low visibility conditions.
The characteristics of navigation lights on a power driven vessel includes sidelights, sternlight, masthead light, and all-round white lights. Navigation lights must be displayed from sunset until sunrise as well as anytime visibility is restricted.
