P129DP129D   Turn Signal Flasher 6 volt

This P129D flasher is new, NOS, Aluminum can.  This flasher has  Black lettering on the can as pictured.  A GMC brand flasher,  round and tall in shape and in mint condition.  It is a 3 terminal flasher with the terminals in the normal configuration.

  This 6 volt flasher  is a heavy duty flasher marketed in this GMC box but other than that I have idea what it fits.

 These instructions are always on the box flashers come in

X — Power (hot lead)

L — Load (to switch operating lamps to be flashed)

  P — to Pilot indicator lamp (this connection may be omitted. Flasher will operate properly either way)
