turn indicator green lens?

[JavierB]

The small green lens on my dash turn indicator has somehow fallen out and vanished.  One of those mysterious disappearances.  it had become unattached, and I disassembled it to try and reglue or reattach but it just fell and is gone.

SO... is that ridiculous tiny part available?  or should i replace both Left and Right ones with some other matching bit of glass or plastic.  what do folks recommend?  

thanks for any tips.
