I am thinking about putting lights under my car and i had ordered them from this place and when i went to pick them up i asked them where do i put them and he said right underneath the car, then i asked how should they stay on and he said to screw them into the bottom. I relized after that i did not want to do that beucase that would cause it to rust, and also i don't want to be drilling holes in my new car, is there anyone that has done this before or have any ideas of a better way to mount them on the bottom. Thanks for your time.
