I am selling one (1) set of '74-'89 front turnsignal boards. There are 48 amber LEDs and should be about 3x brighter than the standard bulb. These will require the flasher relay to be changed to EP26/EP36 available at most FLAPS.
Price: $90 + $10 shipping (CONUS)| $25 shipping (Canada)
These are plug-n-play and fit into the lens. Installation is simple: Remove the lens and bulb; install the boards in the lenses; plug in the PCBs, install the lens.
