Headlight low beams scattering star-like with dark patches

Replacing headlight housings and bulbs can leave low beam patterns scattering star-like with dark patches that do not respond to re-aiming, height adjustments, or moving bulbs within the socket. This leaves drivers unable to fix the uneven output, while automatic leveling systems can also cause dipped headlights to settle too high during normal driving and dazzle other drivers.

What people tried

Every workaround mentioned in the threads below. We haven’t tested any of them — and nobody here is claiming they worked.

The low beam pattern is scatters star-like with dark patches - I have tried re-aiming, adjusting up and down… even unclipping the bulbs and moving them around and forwards/backwards in the socket to no effect.source ↗

I am at a loss and thankful in advance for any suggestions - thanks!source ↗

My 2018 Audi Q5 dipped headlights are settling high at the moment. They automatically lower when I stop the car and adjust when I am on sloped ground but they’re currently pointing too high when driving normally, dazzling drivers.source ↗
