Try leaving it out during the day. It should pick up enough photons (or whatever they're called) to keep it visible through the night.
It usually is outside when I am sailing but I must confess it's likely to be buried under by hats, sweaters, books, Kindles, abandoned sandwiches, etc.
I will try leaving it exposed to the sun today and see how it does. (Should guarantee a rainy day!)
