Simplicity and ease of use are the main advantages of a self-contained light. By definition, they do not need a separate power supply installed. For ranges of 5 NM or less, a self-contained solar-powered light is often the best option. These programmable LED lights — which comprise solar panels, a battery, battery housing, a regulator, electronic controls and a light source in a single compact package — are simple to use and easy to maintain.
If the range is greater than 5 NM, a standalone light with a separate solar power supply will likely be required. The exact range possible and the size of the solar power supply will vary with the flash character.
