It’s a good idea to have a flashlight with you. Something small that you can carry around in your pocket. Preferably something with a cool and geeky design. This LEGO Star Wars Boba Fett Keylight is perfect.
Boba Fett will always be there to help you find things in the dark. Just press his chest to light up his feet. It comes with batteries that are replaceable. Hey, if Boba captured Han Solo, he should be able to help you find your way in the dark.
