A device for illuminating a liquid drink for use at a party or a social event to give the appearance of an illuminated liquid. The device has a light adapted to colimate a beam of light through the transparent bottom of the glass receptacle into the liquid and be dispersed therein. Rechargeable or non-rechargeable batteries are secured within the base to act as a power source for the light. A switch means comprising of upwardly contacts to contact a conductive ring of the base of the glass receptacle forms the on or off means for the switch. A modified form would utilize a coaster which may be used with stem ware and would be activated by the weight of the glass upon the coaster. The still modified form would be formed by a manual operated switch which may be used with the light formed in a chamber formed in the box under the glassware. A charger base utilizing inductive principles is used to recharge rechargeable batteries if used in that particular embodiment.
