It doesn't matter if you choose to use a different led findout the voltage and the milliamps (mA) and you can calulate the data to findout the resistor needed for this mod at one of these two sites:

1. http://led.linear1.org/led.wiz

2. http://ledcalc.com/#calc

the source/suppy voltage will always be 5v (5)

and the rest depends on the led and how many you have

Swap your collector and emitter pins.

Remember for most NPN transistors, when the flat side is facing you... the pins are "EBC". Emitter Base Collector.

For the most part it looks good.
