LED headlights on cars and LED lights in general.
LED headlights when aimed properly are amazing. LED headlights when aimed poorly are the devil. Also fuck trucks with their high ass headlights that are blinding even at a reasonable following distance.
But I’d like to add that LED bulbs in halogen housings aka “poverty beams” should be made 200% illegal. If you commit this heinous act just go straight to the gulag. Halogen housings don’t have the sharp cutoff needed for LED headlights, and pair that with the type of person to do this not being the type to aim the headlights properly and they’re a legit hazard to the roads.
I love buying cheap junk as much as the next guy, but anything that goes in between you and the ground you should not cheap out on. Do your research and make sure it’s a good product before buying.
And regardless of what it is, make sure you toughly inspect and test it at lower speeds before you bomb down a hill at 40mph.
