They're supposed to "help you see better while it's dark out" but completely blinds the fuck out of you when you're on the receiving end.
They literally make it more dangerous to drive because of the brief moments they destroy your night vision and shit.
Fuck white LED headlights.
one of the issues is that they don't take the time to actually aim and align their headlights, it's the worst on lifted trucks. if you change your suspension or ride height you need to do your headlight. Corner cutting pisses me off.
