I had mentioned using LUCAS L594 (?) for the turnsignals. The were used on TR3/AH in late '60s. Last I checked at MOSS they were $35 for each entire fixture. They have single and dual filament fixtures. I went with clear glass with amber bulbs (see my avatar). They also have amber and red glass lenses. There are repro with plastic so beware. They are a perfect fit to the horn grills.
