Lighting signalization device of number of revolvements of car engine titled under PPS - prolonged mental second belongs to the field of lighting or signalization with vehicles. This invention solves the problem of how to point out a signal to a driver in a motor car to get ready for possible braking prior to the stop-light switching on. Device operates in that it develops a contact on the vehicle at the minimum revolvements by means of a microswitch (10) a red bulb (4) switches on that lights until the gas is added and the electric signal on the increased number of revolvements of the axle (3) with cams across the microswitch (10) from the group of microswitches (2) is transferred up to the bulb (4), and it switches off. With further adding the gas onto a footboard (1) of the accelerator increases the number of revolvements of the axle (3) with cams and over the microswitches (11), (12), (13) and (14) successively are switched on other bulbs (5), (6), (7), (8) and (9) that are green. |
