I have got some messages reagarding the voltage of LEDs used.

So, as far as I can remember, I have used special 6V LEDs (you can get it from Radioshack (U.S) or Source (Canada) ). I know it adds upto 18V but they can work normally under low voltage than high. Before putting the LEDs onto circuit, I have measured amps from the points. I cant remember what kinda readings I got but taking that into consideration, I decided to go with 6V 60-90mA LEDs.

You can even put miniature lams instead of LEDs. I decided to go with LEDs because of variety in color as well as longivity. If 12V miniature lamps can be used used. I recommend you connect 3 single lamps to corresponding points (i.e. DS1, DS2 and DS3).

After connecting LEDs/Lamps, make sure they are facing towards the circuit (but not touching it) and not the display so that the reflected light from the circuit is spreaded even on the display and not as 3 beams (looks ugly and unprofessional).

Hope this answers everything. Any other suggestions as well as your tries are most welcome. Please inform me of better ideas as I am just a 3rd year computer science student and not an electrical engineer.

Thanks.
