A lure light device is positioned on a fish line ahead of a fishing lure to illuminate the lure when used at depths or at night. The device has a watertight body containing an LED or lamp device and power cells. A lens on the device contains the light so that it concentrates on the lure. An additional chamber can be used for a scent or fish attractant. A switch turns the light on when a cable has tension from the drag of the lure.
