Surplus sales of nebraska has lenses that fit into the 5065A lamp holders. (Also 5061A/B) LMP-RL-180TT (teal- light green) LMP-RL-180YT (yellow) They show a green one also but it's too short. The yellow needs to be filed a bit as the plastic portion that extends into the holder is a tiny bit too fat. Cheers, Corby
