These are the beginning letters on the VINs of all (except the earliest) rotary powered Mazdas made. Some people refer to the Rx-8 as an FE, but I don't know if their VINs actually start with those letters or not.
I was just wondering if the regular bulbs in the doors and overhead lamp in my 1991 Rx-7 could be replaced with LEDs.
Thanks for the clarification. We've seen those designations before, but out of context we didn't recognize it. They may work, but we only specialize in RX8s, so unfortunately we don't have that information. Sorry about that. :-(
