the gap is slightly noticeable and I think it is intentional actually. I lost one and was putting a new set on the fronts tonight and without the double sided tape you can put the visor flush up to the housing on the signal light.... but then you would have to epoxy/super glue or mount them some other way. With the double sided tape it is about 1/16th an inch or so. But when lit.... it looks nice.
Ok.... I went to the garage and took a pic for ya....
