Lighting was a key consideration while constructing Pac-Mamea.  Obviously, I wanted to light the coin slots and the marquee, but why not light the control panel as well?  For the Tron control panel, I decided to use Happ illuminated pushbuttons.  The incandescent lights that Happ supplied were replaced with lower-voltage red (1000mcd) and blue (2600mcd) LEDs, to extend the life of the lights.
This was done by soldering the LEDs onto a small piece of circuit board, approximately the same size as the "wedge" base on the incandescents.  These custom LEDs were then easily plugged into the illuminated pushbutton bases.

I also wired two 2600mcd blue LEDs to the base of the translucent blue trackball.  All the LEDs connect to my custom lighting board, which draws power from the PC's +5v supply.  There are also connections on the board for the I-PAC's numlock and capslock LED harness plugs, so the P1 and P2 start button LEDs can be controlled by MAME!  Note the transistors for switching the 5V supply to the start button LEDs.


The two translucent trigger sticks are hacked Happ supers with Raider Pro joystick handles, internally lit with glowire that I got from the automotive section at Target.   The driver box that came with the glowire takes a 12v power source, but won't run off the PC +12v line.  So I had to get a 12v power inverter from Radio Shack, which has a cigarette lighter plug, so the driver plugs right into it.   Probably would've been cheaper and easier to get a PC mod kit from www.glowire.com and then it would also power on with the PC!


When I received my coin door, it had no lights installed.  Since I had so many LEDs around (left over from my plans to illuminate every single pushbutton), I decided to use LEDs to light the coin return buttons as well.  To do this, I first removed the original lighting brackets.
Next, I wired two bright (3000mcd) red LEDs together in parallel, soldering each to a short piece of PCB with mounting holes drilled in the ends.  A 100 ohm resistor was soldered to the positive lead, to protect the LEDs from the separate 3v power supply.
The leds were connected to the coin door via the original mounting holes and screws supplied for the light brackets.  This puts the LED in a proper position to light the interior of the coin return button.
