I am installing under cabinet lighting that will be placed underneath the trim piece at the front of the cabinets. I am not sure how to handle the lighting on the shelf that spans the cabinets in the beverage section of the kitchen. Do I put lighting under the shelf and if so, where? There is no trim piece under the shelf so any lighting would be visible. In addition, the shelf is set back 4 inches from the front of the bordering cabinets (a close-up of the shelf is attached). A backsplash is being installed as well. Please help! Thanks!
