The LED's are from Jaycar they are 10mm ones. I used the following:
ZD0201 for the tail light these are a 4000 mcd LED 50mA and 2v
ZD0202 for the brake light there are a 10000 mcd LED 150mA and 2.6v
ZD0212 for the idicators these are a 9000 mcd yellow 100mA and 2.6v
ZD0220 for the number plate light these are a 5000 mcd white LED. 30 mA and 3.5v
Because the LEDs use fuck all voltage you need to use a dropping resistor on the positive side before the LEDs ( the long leg on the LED is the positive one) if you go to this website it will tell you what size resisitor to use with them just put in how many you are using with the mA and V numbers that I have put up the top and it will tell you what size resisitor to use you will probably need a 1 watt resisitor to be on the safe side and you will be able to get them from Jaycar as well. I hope that this all helps.
