Here are two types of finished light rings and lenses for drink holders.
An acrylic lens mounts to the bottom of the drink holder and diffracts four LEDs that are bottom loaded. You drill out the bottom of the drink holder. The lens has built-in drainage holes. This works well with transparent contents like bottles but won’t shine through solid objects like aluminum cans. The interior dimensions of the cup holder are unchanged.
Acrylic lights rings fit under the top lip of the drink holder and raise the drink holder up 3/8-inch. The exterior top is beveled. The interior is rabbeted to accept the flexible LED strip. All machining marks are polished out. The exterior is frosted to diffuse the lights.
These are refined parts. Upon close inspection many others look rough and show the router marks.

She also has the right size of LED strips in all colors.
