Ensure lights are turned off when not in use to maximize battery life (especially with solar lights as you want to make sure you have light when you need it.)
-Be cautious of liquifd around the lights. (Some are water resistant some aren't so best to use caution with all. Water resistant does not mean waterproof.)
-Make sure lights are properly secured when hanging from a high point or inside of a tent.
-Keep away from fires.
