Tuning or reworking the rear lights Top LED type with chrome bar.

Hello everyone. Has anyone worked on or researched modifying or redesigning rear Top LED lights so they can reliably and correctly support dual C-element operation, serving as both parking and brake lights?

Standard software settings for adjusting brightness and assigning functions and execution priorities are ineffective, as the driver inside the light automatically increases the reduced brightness (voltage) to the required level, or goes into protection mode and returns an error.

Perhaps someone has researched this issue more deeply than I have and found a solution, either a board resoldering service or ready-made solutions.
