Anyone notice a very slight slow flickering of headlights in their 2005 R/T? This occurs w/o air conditioning engaged most noticeable at idle. Any thoughts? Am I hallucinating?

 

A low idle can do that with the a/c on. Every time the compressor cycles it puts an extra load on the motor and the rpm's will drop slightly at idle. With a slightly lower idle, the charging system has to work a bit harder at charging the battery. The extra load would/could cause the headlights to cycle slightly.
There 'might' be a TSB out on flickering headlights as well.

I have seen this issue on every car I have ever owned.

 

Thanks. It's not a major issue but something that caught my eye.

 

only time i ever noticed it was with a thumpin system, just added a really big capcitor before the amplifiers and fixed right up
