I’d heard that about led lights as well. The technology must have improved over the last 20 years. Back then I was an avid bike rider and used those blinks led lights when riding. They typically lasted about a year or two before I had to replace them. Maybe it was all the jiggling and bumps from NYC’s potholed streets?
In our current house we have LED lights everywhere but they are mostly screw in bulbs for floor and table lamps since they didn’t build houses with many overhead lights back in the 70’s.
