So I have been putting off this issue for a while. We are almost roadworthy except for the dang blinkers. I had led in the front and regular bulbs in the back, the right rear bulb was blown, so when I turned on right blinker only right front would work. By turning on left blinker ( led in front, bulb in rear) all working blinkers, except blown rear right bulb, would flash a normal flash, not fast, normal speed. I have swapped the flasher relay for a custom LED elfr-1 led flasher relay. I have also tried putting inline led load equalizers to no avail. At this point I might just mount painted flashlights on to use as blinkers. If anyone has any advice or can point me in the right direction it would be very appreciated.
