Image 1

This board is fairly simple as well, not much other than LED's and the corresponding resistors. Not much to say, but power is supplied from other boards to light the desired LED. Please note the use of white plastic spacers between the LED and board. This makes life easier when soldering keeping all the LEDs at the same height.

Led Ind Circuit

Holes are drilled in front of the box and the board is attached a single nut, bolt and spacer to the front. I didn't find it necessary to have any more as LEDs were quite tight.
