I'm currently working on a full exterior led conversion excluding headlights and fogs. I've ran into a bit of confusion as far as rear turn signal bulbs go. I'm aware that they are dual filament in the case of a halogen bulb, what what about led? Would I be able to just buy a 4057 led bulb of any kind and be good to go? Or is there something I'm missing?

 

Nevermind, I seem to have found the answer. They do make dual output leds to my surprise. http://www.superbrightleds.com/morei...ed-tower/1263/

 

Yes. I got the ones from VLED (their 21 SMD platinums, 4 of them). You will need one 3ohm resistor on each side, doesn't matter which of the two LEDs you splice into as they're all ultimately the same wire anyway. Very pleased with them, quite bright.
