Colecovision ON/OFF indicator LED or Power Switch LED

When the Colecovision is OFF but plugged in, it still draws power. This can be a problem if you have an illuminated Switch you want to install in place of the old Power switch. The problem is that the led will stay on even when the switch is turned off. The location indicated in this picture near the expansion slot seems to be a good point to use for a led (remember to use the correct resistor with the led or it might burn out).
