A level including level vial(s) having enhanced visibility are provided. The level may include a level vial including a material that is attracted to the interface or border of a globule within the level vial which improves visibility of the interface. The level may include a solid level indicator having easy to see end surfaces that are generally vertically oriented when in the level position. The end surfaces of the solid level indicator may allow the user to more easily compare the position of the solid level indicator to indicating lines formed on the level vial. The level may include a level vial including a first liquid and an immiscible second liquid forming a globule with the first material. The globule formed from the second material may improve visibility compared to a typical air bubble.

A golfing level assembly includes a cap that has a brim which extends above a user's line of sight when the user is wearing the cap. A pair of hinges is each disposed on the brim and each of the hinges is positionable in a deployed position or a stored position. A bubble level is coupled to each of the hinges and the bubble level is spaced downwardly from the brim when the hinges are positioned in the deployed position such that the bubble level is positioned within the user's line of sight. The bubble level has a reference line extending along a full length of the bubble level and the reference line is aligned with the visible horizon. In this way the bubble level indicates the degree of slope of the putting green to assist the user with successfully putting on the putting green.

A level device for a spirit level includes a level device body, and a substantially cylindrical cavity formed by an inside wall of the level device body. The cavity has a longitudinal axis and serves to accommodate a liquid, and the level device body is arranged in a carrier body. The carrier body includes two transparent covers for closing the carrier body and preferably includes a casing body which is preferably in the form of a circular ring. An outside wall of the level device body has a curved region with a curvature in the longitudinal direction relative to the longitudinal axis of the cavity, by which a magnifying glass effect can be achieved when viewing a marker body which can be arranged in the cavity.

A vehicle safety device for detecting vehicle tilt automatically shuts-off power to an ignition system and fuel pump and summons emergency assistance using a bistable switch circuit that toggles between a first bistable switch position in response to a reset signal and a second bistable switch position in response to an alert signal. The safety device can remain in the bistable switch positions without a power source and employ an encrypted bi-directional protocol to summon emergency assistance and generate the reset signal without vehicle operator intervention.
