Use the Apple Watch as a Flashlight
With watchOS 4 you can use your Apple Watch as a flashlight. It's not super bright, but it will help you get a little more light in a tight space if you are trying to use a screwdriver or find a plug behind your entertainment stand.
This can also provide a mall safety light when you are walking at night. You can choose from flashlight, flashing light or a red light. To do this, swipe up on the Apple Watch and then tap on the flashlight. Swipe to the side to switch between the different light options.
Swipe down to dismiss and turn off your Apple Watch flashlight.
