Hi

I have a 2007 Chevy Tahoe that is having an issue. When I put it in drive and have my headlights on they seem to pulsate only when the gas is given. The same thing happens when the interior light is on. No troubles starting the car at all.

Any clue what this could be?

Thank you

That may be normal, you could have your charging system checked. Some of the national brand autostores might check it for free. You might have them check for codes, also.

The higher the rpm the more the alternator puts out, up to a certain point.
