The only problem is that when the headlights were on, the polarity of the reflector bulb changes. Basically, I could either have a turn signal when the headlights were on or when they were off but not both. I'm not sure if this is because of the type of LED I used (it was a 194 replacement with the resistor built in) but It wasn't worth the trouble of changing it since it is hidden behind the reflector anyway. A normal filament bulb doesn't care about polarity but the LEDs do.

The halo LEDs work fine either way and they connected directly into the other 194 bulb slot so you should be able to replace that with no problems. As rocketfast123 said though, it may be brighter than you really want and could look strange if the LED is brighter than your normal headlights.
194 do not need resistors. Only the 3157(s) need a resistor.

Just to add to this quick, and I know this is basic and a dumb question but it honestly has escaped my brain.

If you replace all of your bulbs, with bulbs that contain LED's, do you still have to alter your electrical system for the faster blink rate, or can you just install all LED bulbs and go?
If you replace all turn lights with leds you need 4 resistors.
