I assume you like the clear lens over the turns, do you plan on using an amber tint bulb or going against the grain (white turns in back being illegal)?
I did a repair to a set of (unknown origin) tails for a BMW E30 3 series a while back. The lenses were all a light smoke, no color in any of them. The lights came with clear (reverse), amber (turns) and PURPLE bulbs for brake and tail lights. I had to tint some clear lamps to make them the right color red for them to be legal. The turns and reverse were fine as is.
I swear, the brake and tail light bulbs reminded me of Christmas lights from my childhood! Fun to look at, but they didn't belong on a car - not on this planet, anyway!
I sell high output bulbs if you are interested, clear or red, factory specified 3496 and 3497 (if you care about that sort of thing), some high output running lights, and some standard amber bulbs for turns with a clear lens. They are good in tail/brake dual filament, reverse, tail, front turns. I also have 9011 and 9012 high output headlight bulbs, if you need more light up front.
Just shout if you are interested when you find the lights you're looking for.
