Hello. I have a problem with flickering lights both inside and outside. This happens when you click the window down or up or when the gearbox changes gear, e.g. from 4th to 3rd or from 3rd to 2nd. Then you can see that the lights dim.

I have already made several modifications that were supposed to help but unfortunately they did not help, including:
- I installed a new alternator
- a new battery
- I cleaned all the ground points on the bodywork
- I added additional ground wires and plus to the alternator
- I cleaned the light switch

The only thing that still comes to my mind is to install an additional voltage regulator in the car because as you know, in our cars the voltage regulator is built into the computer.
