My rt directional flashes quickly like a bulb is blown out.. The rear bulb assembly seems to be in good working order, the front unit does not allow the bulb to be inserted properly, just doesn't seat correctly in the socket. was trying to remove another unit in the JY today but still too much snow and ice on the ground to allow full access up inside the bumper, was amazed at how difficult it is to get this thin out, seems it's bolted to the bumper along with the rubber trim, got one nut off but could'nt get to the other inner end, plus the unit does not have a connector plug, it's hard wired right into the harness, at least on my old Volvo the whole assembly unplugs about a foot away from the unit.... Screwey design..
