The Breakout EDU kit comes with a UV Flashlight. The flashlight runs on 3 AAA batteries. The kit ships with 3 starter batteries, but can be replaced with any brand AAA batteries when the UV Flashlight stops shining brightly.
Please follow the instructions below if you need help getting the flashlight to work.
Unscrew the cap at the rear of the flashlight.
Remove the plastic battery holder.
Install the 3 AAA Batteries into the battery holder by placing the negative side of the battery on the spring and pushing the positive side of the battery into the compartment with the '+' on it. Repeat for all 3 batteries.
Insert the battery compartment into the flashlight with the '+' side facing towards the front of the flashlight (shown below).
Replace the rear cap and screw it back into place.
