Ever since I bought my 2001 LX470 my front blinkers haven't worked, my rear ones flash quickly but do work just fine. I replaced the flasher relay with an OEM one last week and it didn't change anything. The front blinkers work as indicator lights, flashing when locking or unlocking but don't blink with the turn signal at all. The headlights were converted to LED by the previous owner as well as the front turn signal bulbs. I've also tried replacing the front blinker bulbs with another set of LEDs. I've included photos of my blinker bulbs. Any suggestions on what to try next? thanks.
