It is more like a sharper slapping or tapping noise and is very rapid. It is air getting under the marker lights and they are vibrating up and down hitting the roof just above the windshield. This is not something that is supposed to be happening so don't base your decision on it. I had originally put some door edge trim along the front edge of the light assembly before driving to NC as I recalled someone fixing it that way late last summer. Didn't work for me and they left it on there when they tried fixing it last time. I took it off Saturday and the noise is actually quieter now. It is still there and needs to be fixed but now you can actually carry on a conversation when it is doing it but you couldn't before.
