Disclosed are smart tail lights characterized in that they communicate variable braking intensity, which comprise control means capable of assessing the braking intensity exerted by a driver, such that, depending on the braking intensity, the rear brake lights illuminate in an increasing number, with increasing intensity or both correlatively, to minimize the possibility of a rear-end collision. The smart tail lights, with variable braking intensity and reverse lights, are formed by a braking intensity sensor, a modulation and control module, tail lights and electromechanical connections, the sensor having electromechanical means integrated into the brake circuit of the vehicle in order to detect the braking level, and the module having means for converting an electromechanical input signal into an electrical output signal for activating the rear brake lights.

There is provided a rear sign lamp capable of enhancing safety. An LED string (502) includes four LEDs (504_1 to 504_4) connected in series. An LED driver circuit (610) receives a battery voltage (V.sub.IN) and supplies a drive current (I.sub.LED) stabilized at a target current (I.sub.REF) to the LED string (502). A bypass circuit (620) is provided in parallel with a bypassed portion (503) including two adjacent LEDs (504_3 and 504_4) of the LED string (502), and sinks a bypass current (I.sub.BYPASS) according to a battery voltage (V.sub.IN).

Disclosed is a case structure for a rear combination lamp in an automobile in which a rear combination lamp case in a corner portion formed in a rear portion of a vehicle is formed in a corner case having a substantial triangle pyramid shape by a rear plate, a side plate and a planner plate, wherein the rear plate forms a case rear face on which a concave notch portion is formed in a substantial center, wherein the side plate forms an air communication side face which is formed so as to gradually become narrower width toward a rear thereof, and wherein the planner plate forms a concave air communication path in a center thereof so that a terminal end of the concave air communication path communicates with the concave notch portion of the rear plate.

An illumination device for vehicles, in particular rear light, with a light-emitting unit to generate a predetermined light function. The device comprises a plurality of light sources and an optical unit. The optical unit comprises a light guide with means for the deflection of the light coupled in the same, and a retroreflective unit to generate a retroreflective function. The light guide is designed as a low-profile light guide, which is arranged in the main radiation direction in front of the retroreflective unit. The means for deflecting the light are distributed on or in the low-profile light guide such that the first light beam emitted from the light source and coupled into a narrow side of the low-profile light guide is coupled out at a front flat side of the low-profile light guide to produce the predetermined light function. A second light beam coming from the outside passes the front flat side and a rear flat side of the low-profile light guide and is incident on the retroreflective unit and is reflected by it back through the rear flat side and the front flat side of the low-profile light guide in the main radiation direction to generate the retroreflective function.
