Meso Custom turn signal

So I installed the Meso custom turn signal about 2 months ago and have been getting a high pitched whistle when going 55mph. It is primarily relevant when the windows are down however it sounds very whispy compared to the driver side. I have looked at the foam to make sure their are no holes or damages. Is anyone else having a similar issue or know how to possibly fix it. Thanks.

 

Passenger side? Mine did that when it was stock, and continued to do it after the MESO signal install.
I think it's the factory trim. Haven't bothered to isolate it yet.

 

You should have not have any issue with wind noise. The stock turn signals were 3D scanned so my replacements are the exact dimension down to a T. Make sure all the clips seated and the mirror is sitting flush like stock.
