thanks Ghost , here a few pics of the box part number is 800C-R6 , yes theres a bulb in the end
went to ebay and typed in SIGNAL-STAT SIGFLARE and came up with 8 of them.One seller even had the bulb screw in cover in green for $8.00 here is one complete BUT PACKAGE SAYS 6 VOLThttp://www.ebay.com/itm/rat-rod-custom-signal-stat-turn-signal-hot-rod-/201307217438?pt=Vintage_Car_Truck_Parts_Accessories&hash=item2eded85e1e&vxp=mtrmike I looked at them on Amazon they have 8 in stock now
pretty sure you just swap out the 6v flasher for a 12v and should be good to go.
