Saw something about this recently as well as the direct harm to wildlife that is caused by paving roads that were once gravel which allows for drivers to go much faster and ultimately results in more vehicle strikes either maiming or killing wildlife that used to be able to safely cross

I haven't explored LEDs too much, but have an education related to transistors. Because they are diodes, significant overvolting will degrade the diode itself and if it were to happen often enough could damage the junction to the point of no longer working. Fluctuating voltage could damage other parts of the device, but I'd guess overvolting is the bigger danger

I kept trying to read this to the tune of Slow Motion and couldn't figure out why it wasn't working for an embarrassingly long time
