I've been searching for hours trying to get a straight answer on bulb codes for the 370, but I can't. Trying to order led's for an all around swap on my 2011. I understand that the parking lights, map lights, trunk light, and license plate lights are all the same, just different wattages (correct me if I'm wrong). What I don't understand, is the difference between the front and rear turn signals. I'm ordering all from v-leds, because I want to ensure all my bulbs are going to be the same color and quality. On the Sylvania guide, it says the rears are 7440A, and the fronts are 7444NA.
These are the bulbs I'm looking at.
AMBER PLATINUM 21 LED BLINKER TURN SIGNAL BULBS 7443 7444 7440 7443NA | 1 PAIR - 7443 - 7440 LED - Shop Bulb #
I don't even see an option for 7444NA. Are these compatible anyways? Do our cars use the standard or ck type base?
If I'm replacing ALL FOUR turn signal bulbs, do I need 6ohm resistors or 3ohm resistors? If it's 3ohm, where do I buy these? V-leds only sells 6ohm
