Beacon Lights illuminate inside the cabin / P3D4.5

I noticed the beacon lights bleed through the bottom of the cabin. I can see solid red and flashing under the rear bench seats. It looks like there's red floor lights installed in the cabin :). I also notice the flashing down by the rudder pedals but it's fairly dim and not bothersome. The only workaround I could find was to remove some of the beacon.fx files from the main effects folder which obviously diminishes the exterior beacon effects. Maybe this is a LM issue?   I'm running 4.5 with latest version of the Lear.
