Having climatronic you can access car voltage for troubleshooting by pressing few buttons.
Takes Plutoe to need professional for it.
Your symptoms can be interpret in 2 ways.
1. your lights dim because voltage drops,
2 voltage drops because the engine drops to very low rpm.
When observing voltage might give some indications, check car for pending codes and listen if sudden rpm drop is not trigger by attachments like AC compressor, or bad pulley.

Car does not have any codes and pending codes , run s like new ....
yesss im thinking about number 2... Kajtek1, that lights dim becouse engine rpms drops to very low idle for a second or two then without pressing gas pedal and still holding brake at the stop light it goes back to normal by itself .....
So are tou suggest to set my climatronic to voltage and observe it while im driving ??

You are the one behind the wheel. I don't know how good are your senses and what is your experience in interpreting sounds.
When observing voltage does not cost much beside moving your finger few times, if you suspect mechanical resistance, taking the belt off and moving all pulleys by hand would be advised.
