Step 2: Make the LED Line
Take your altoids box and in the front drill a hole for each LED about 1 CM apart from each hole. And drill one hole in the top for the switch
Now match the holes with the PC board and place the leds in the matching holes in the PC board just to make sure they match up with the holes on the altoids box.
Take the PC board with the LEDs in it and solder the leads. Use jumper wire to connect the gaps (or just use a large amount of soder if you don't have any). Now in the middle just after the last LED that's before the red LED, solder a wire about 2 1/2 feet. And do the same on the left (same length), these 2 wires will be the switch on the outside that will make the RED LED turn on for brake. On the left solder a wire about 6 or 7 Centimeters this wire is for the resistor and power PCB. And then on the right solder another wire about the same size.
