I hear ya... Well, I can speak in general with our cars in lighting and using LED's, etc... From what I understand, you can upgrade to rear blinker LED's with no resistors if you keep front stock, but if you add front switchbacks in, you will need resistors in the front regardless if rear blinkers are upgraded to LED or not... We also don't have canbus, so definitely less chance of any issues at all with switchbacks that do have resistors built in.. it's also nice we can use any
headlight bulbs we want too, of course, I'm the nerd who says you better research the the proper LED's for reflectors of course, but I digress... So yeah,
THESE Syneticusa ones for $31 is what I would try first if I still had the factory reflectors, I bet it's "only" 4 stars cuz people with advanced canbus systems that it didn't work with and should be fine for us... And besides, Amazon has it's awesome return policy, easy to send back for not meeting expectations if you don't like them
