CMG O4 Mini Task Light - Bright White - With Key Chain -Waterproof

CMG O4 Mini Task Light - Bright White - With Key Chain -Waterproof The O4 is a good looking light, so you need not be ashamed to carry it around on a zipper, keychain, bag handle, etc. The O4 is ready to go right out of the pack. To get a momentary burst of light, just give it a squeeze. If you wish for it to stay lit continuously, swing the small metal lever on the top of the light downwards so the end of it covers the rubber button. This lever applies enough pressure on the button to light the LED without having to keep squeezing. Swing the lever back to the top position to turn the O4 off. To change the battery, remove the phillips screw from the back of the O4, and use a flatbladed screwdriver to carefully pry the two halves apart. Be careful so you don’t damage the rubber gasket that seals out the weather. Remove the old battery, and insert the new one, button side (-) facing towards the little circular thing with the LED on it. Reassemble by aligning the two flashlight halves and firmly squeezing together; install the screw and tighten gently but firmly
