Definitely good light output. They take the projector model from others car model and mod into yours. Especially coming from reflector halogen headlights, this is a major upgrade.

But if buy car with stock reflector LED like civic, new x70, x90, this will be some improvement for light output distance.

The best is always LED projector headlights in term of light output and distance. But not sure why Mercedes Benz light output is always the best vs others

Based on own experience yeah, but maybe Audi that I ride are older version. Try ride any newer Mercedes at night, and see their light output. Almost twice brighter than my Honda, even with stock LED projector headlights
