I doubt this is as much of an issue in Europe, but here in the States the headlights of the average pavement princess (large truck that hasn't ever seen a day of work) shines directly into the rearview mirror of a regular height car. Nothing aftermarket at all, just stupidly large vehicles being a nuisance.

I still prefer halogen bulbs because they're so inexpensive to replace, while if your LED goes bad it's gonna be expensive costly.
