Some of the double sided tapes are so good that they're difficult to later separate when you need to remove things, like to change the bulb. Too easy to break things. My preferred weapon for such jobs is black butyl mastic. Sold in rolls as black butyl sealent tape in typically 1" wide x 40ft rolls, available at most decent hardware stores. You can cut narrower strips with a razor knife to suit the job. Makes an excellent waterproof gasket and adapts to irregular surfaces. Some of my interior plastic trim is being nicely held with mastic where the plastic clips have broken.
