A few evening pictures below. My assessment driving around the neighborhood is that they are quite good. The right headlight is a bit more challenging to maneuver into the headlight hole, but they are both very snug and I doubt will budge even on a hard jolt.
The light distribution is noticeably rounder than the original. Key is to install them so they are aimed slightly downward so you don’t blind others in traffic. I used the clear cut off line from the halogen to aim the first one, then aimed the second based on the first. A bit of trial an error. Also - aiming them downward leaves a bit of a gap between the front cover and the headlight. I hope it’s not a problem for rain to get in there...
The beam is overall brighter and perceived wider. For about €50 each, I think these are viable replacements, however likely not street legal. And I do miss the daytime running light option to draw even less power during summer days. But for what they are, they’re pretty cool.
