Bill, I think two bright bulbs on at the same time would be discernible as a turn signal. But it would be good to check before proceeding.
Ken, I would likely use leave the upper brake single contact socket alone, and change the lower tail light socket to a dual contact and run an 1134 in it with the brighter filament as the turn signals and the less bright one as tail lights (the same way a single turn/brake and tail dual filament bulb would be.)
John, I sincerely apologize that the flash didn't come to me back then. But then how would we have had this interesting discussion? wink

If you're smart enough to take it apart, you darn well better be smart enough to put it back together.
