First attempt at lights

[jerry56]

Ok I got the lights working sort of. I can turn them on and off with the switch, I'm using this current limiter

and I can hook up my red tail lights and my amber parking lights in parallel and they work.... but if I put the white headlights in parallel with them the headlights won't come on but the other lights will... if I reverse the pos-neg the white lights will work but the red and amber won't. I tried reversing the leads on the white lights but they won't come on if the red and amber are in the circuit.. the red and amber are 2.2v and whites are 3v all 20ma... I even tried using a resistor and get the same result... Is it not possible to put white/red/amber all in parallel on the same circuit ... do the white lights have to be on their own circuit...
