PURPOSE:To prevent a driver on a succeeding vehicle fromsleep in night travelling by constituting one unit of tail lamps from a plurality of adjacent lamps to turn on and off selectively one of these lamps are random for sequentially shifting a point to which the driver's eyes are directed. CONSTITUTION:Tail lamps L provided respectively at the rear left and right portions of an automobile are constituted from adjacent, for example 9, lamps l1-l9 respectively. A random number generator 1 for generating a numerical value 1-9 on by one at random every predetermined time is provided in a lighting circuit of the tail lamp L, and the numerical value generated by this generator 1 is decoded by a decoder 2 so that the output is produced only from an output terminal (t1-t9) corresponding to the decoded numerical value. The respective output terminals T is connected to holding circuits H(h1-h9) for holding signals once it receives signals until the generator 1 generates the next random number, and dive circuits D (d1- d9) are turned on by the output of the holding circuit H to light one of lamps lx(l1-l9). |
