#4: The Bright Lights
There are a lot of good things about LED lights; for instance, they last significantly longer than standard lighting. In fact, they can go for years without needing to be replaced, which means fewer lightbulbs in landfills and less money you have to spend. But when it comes to car headlights, things aren’t so rosy.

A lot of cars these days have LED headlights, and a lot of other people are really unhappy about that, as it seems like these headlights are a lot brighter than the ones with halogen bulbs, which can be blinding to other drivers at night. I don’t think spending less on light bulbs is worth making other people crash their cars.
