I'm hoping to put together my HID set-up this weekend with Sonar projector headlights. I've been doing my research but what is this "double sided tape" everyone speaks of? Something about cutting down buzzing, but what is it used for? What kind of tape is it?

 

 

Mine came with double sided tape. This is where Is stuck mine. Idk if you ls1 guys have the same amount of room or not

 

I mounted mine on the side of the frame near the lights. Unfortunately they fell off about a month after I put them on there. I'm going to redo them with either velcro or zipties.

Still on nice and snug after 3 years.
