Somebody rattling my cage? Hello? Mark's reason for the statement that the rear lights might be involved is the fact that some flashers won't sequence if one of the bulbs is burned out, but I think the 67s must use a very heavy duty flasher, because so many bulbs are flashed (the normal light duty ones wouldn't handle the load, or would flash extremely rapidly, due to the extra current.) For this reason, I doubt the front indicators are affected much by what's happening at the rear of the car. These bulbs are indeed wired in parallel, as D-squared pointed out. They are fed off the same circuit as the other front turn signal filaments, and so if the other front flasher lights are working, the fender top ones should be working also. Even though I have 4 cars with these, I have never had a failure, so I regret I cannot tell you what bulb is used, but it should be in your owner's manual or your FSM.
