Abstract: A lighting device includes a base (1) and a light (2). The light (2) includes a housing (21) receiving a controller (22) electrically connected to a lighting element (24), a chargeable battery (25), and a switch module (26). A female coupler (3) is provided on one of the base (1) and the light (2). A male coupler (4) is provided on the other of the base (1) and the light (2). The female coupler (3) is detachably engaged with the male coupler (4) to detachably mount the light (2) to the base (1). The light (2) is detachable from the base (1) and can be used independently.

Abstract: A tire-pressure signal transmitting device includes a tire pressure detector mounted in a tire of a vehicle. The tire pressure detector detects pressure in the tire. A transmitting device includes a data receiver and a wireless transmitter. The data receiver receives data containing pressure of the tire detected by the tire pressure detector. The wireless transmitter is connected to the data receiver by a transmission interface. The transmission interface converts the data from the data receiver into a signal indicative of the data and transmits the signal to the wireless transmitter. The wireless transmitter sends out the signal indicative of the data. A portable electronic device receives the signal sent by the wireless transmitter, allowing a user of the portable electronic device to know the pressure of the tire.
