Yeah, I heard they were Mercury-Vapor and the reason they will be gone by the time I'm 40 (which will be in 2030), is because the new lighting you see on platforms after they have been rehabilitated use LED, have solar panels, and obviously do not contain carcinogenic properties. The lights' half-life is longer, and are more compact. Still I think they can make a mushroom-shaped light with solar panels. Hopefully they put one in the LIRR museum in Riverhead. I'll never forget the 22.3-mile run I did along the entire Babylon Branch and having someone take my photo in 2008. Made me stand on a garbage bin holding the sign with one hand and my ticket in the other on a mushroom light.
But getting back to the subject...hopefully it can be preserved and not fall into despair like East Williston.
