Probably been discussed but we all know about 'search'.
Coming home tonite from my local cruise nite I was driving with the hi-beams on (such that they are) and I goosed the gas to clear the cob-webs out of the car and I noted as the car down shifted the headlights dimmed noticeably. Tried it a couple of times with the same result, same for low-beams too. It takes a few seconds for the lites to charge back up to full brightness. Is this normal? Never noticed it on the 04 MM. If it's not normal where should I start looking.
Thanks in advance
