The title of this post pretty much covers my question. What I want to do is add a "Knight Rider" light bar in the grille, but I want to make sure the sensor in the black grille won't be affected. It is just a LED strip in a water proof clear plastic cover. Maybe 1/2 inch tall at best. If you think it would affect the sensor, then ideas on where to put the light strip would be helpful. It is 24'' long. Thanks, all!
