Locate battery end.
Unscrew end.
Remove spring.
Once the spring is removed you should see the padding for the ligthbulb. This looks different depending on the flashlight.
In this particular flashlight, the bulb protection is a plastic tube. I've seen some with a piece of foam.
Remove the bulb and reassemble the flashlight. Remember to buy a two-pack of bulbs the next time you need one so you can replace the spare in case of emergency.
