The adhesive on the LED strip lights is very effective for mounting, but it tends to leave a lot to be desired at times. It will need to be strengthened over time if it does not stick well with certain surfaces, as it does with most adhesives. In this case use the following:
Extra Adhesive Tape – (3M tape that can be out on the surface before the strip to double the bond)
LED Strip Mounting Clips – (Mounting brackets for strips)
