Step 5: Wire LEDS to the Battery Case
Take the end of the red wire lead from the case and insert it into the open end of the butt splice that is attached to your positive LED leads. With your pliers, squeeze the splice firmly over the red wire. Next, insert the black wire in the other splice, and squeeze.
Now gently bend the leads at each splice, so it looks like the picture. It is very important that the two splices never touch, if they do, it will prevent your LED Art from lighting up, and quickly drain the battery.
