Alright I am making 4 angle eyes for my projectors. I'm either gonna make them purple or white; it'll look sweet. Anyways I wanna hook them up to my corners, all the calcs online show me how to wire it up if i replace the stock 194 bulb.

Problem is this diagrams dont show the stock 194 bulb. So i think the resistors they are telling me are wrong. Does anyone know what kind of resistor i would need if i hooked up the stock 194 bulb in parallel with the leds? Or if you know a better configuration I'm all ears as long as the 4 leds and the 194 bulb light I am happy. Or a better calculator?
