20 volt work light that attaches to your battery the same as you drill or other tools.

Pla is used for the bottom and middle parts.

PETG transparent is used to the top cover. 

1 LM2596 DC-DC Buck convertor step down module is required.

1 Rocker Switch AC 6A/250V 10A/125V SPST 2 pins. I used the pre-soldered wire ones. 

6 led bright white strips cut to fit as per the picture. 

3 #6 x 1.5" button head metal screws.

2 Male quick connectors for 22-18-gauge wire.

1 roll of red 22-gauge solid wire.

1 roll of black 22-gauge solid wire.

To set the voltage out on the buck convertor you need to connect the battery to it and with a tester you 

will need to turn the trimmer until you get 11.5 volts. I set it to 11.5 so the Leds don't get to warm.

If you are using 5-volt Leds then adjust the voltage to 4.8

See reference pictures.
