A two compartment vessel has an upper compartment for containing a liquid and a lower compartment for containing an electrical circuit including a lamp. A light transmitting wall separates the two compartments. A set of spaced electrical contacts disposed on the vessel are connected to the electrical circuit. Responsive to the lowering of the electrical impedance between the contacts as caused by moisture bridging the gap between the contacts, the lamp is actuated to shine light into the upper compartment. In one embodiment, the contacts are disposed on the light transparent wall for causing activation of the lamp responsive to the electrical conductivity of the liquid in the upper compartment. In another embodiment the set of contacts is disposed on the handle forming a part of the container, and actuation of the lamp is responsive to moisture at the surface of the skin of the user grasping the handle whereby a lowering of the electrical impedance between the contacts occurs.

An illuminated beverage vessel comprising: a first compartment for holding a liquid; a second compartment disposed below said first compartment and containing a lamp and an electrical battery generated circuit for energizing said lamp; a light transmitting wall separating said first compartment from said second compartment and forming the bottom of said first compartment; a pair of electrical contacts electrically insulated from one another disposed in said first compartment for being contacted by liquid disposed in said first compartment, and further contact means disposed for coupling said pair of electrical contacts to said electrical circuit for causing said electrical circuit to energize said lamp for transmitting light through said wall into said first compartment responsive to liquid in said first compartment bridging the insulation between said pair of contacts and thereby lowering the electrical impedance between said contacts.
