Class 104 lighting help

[NickL2008]

Good afternoon all, 

 

I require some help with a lighting project. Im adding bi-coloured head/taillights to my Hornby class 104 conversion, and just need some help getting it to work. Pictured below are the LEDs that I will be using. So far I have identified the + and - terminals and have temporarily attached the resistors that came with them to ensure whilst testing, that ai don't blow the LED's. Can anyone help please? 

 

Edit: Just to also add it will be for a model DC, becoming DCC in the future

 

Thanks in advance

Best carry out  a Google search, plenty of YouTube videos that will help, however, both your yellow LED circuit and red LED circuit can share the common

You only need one risistor in the common lead for Bi-colour LED's. I take it these are common anode devices? Common positive. You need common anode for DCC. The common then goes to the DCC blue wire and the cathodes go to yellow and white wires.
