I don't know what fender blinkers are, but since you didn't get a response here, you might consider asking on miata.net. BTW, you didn't mention what generation car you have, and that may make a difference.
Does anyone here have experience installing the OEM fender blinkers that are equipped on our cars overseas? I've seen the diagrams and write ups, but I want to see if anyone here would give me a hand with it, mainly because I'm not too confident in cutting up my fenders. Let me know if you'd be willing to help out. Thanks
