montajul este foarte simplu si functioneaza asa: cand puneti frana, cel de-al treilea stop clipeste de cateva ori dupa care ramane aprins (aceasta pentru a vedea cel din spate mai repede ca ati pus frana)aveti poza ca exemplu de functionarebaftaWhen we step on the car' s brake, then together with the classic rear STOP ,the third STOP which is situated in the middle of the back half of the car also switches ON. This is the classic function , is to be found in all modern cars. The difference with the circuit is that when we "step on the brake " then the third STOP switches ON and OFF rhythmically once a second , three times, it then reverts to it' s normal functioning, remaining constantly switched ON, with the provision that we will continue to " step ON" the brake. If we leave the brake, the STOP switches off ,waiting useful for drivers who come from behind and are relatively alert their attention, with the result that we avoid a visit from behind, with the corresponding consequences. The switching on and off and the length of time can be adjusted champing the use of the capacitance at C4/ C5, being careful always that they are not too big, because then the switching on/off becomes annoying for the drivers behind. The operation is done carefully cutting off the continuation of feting +12V which leads to the third STOP and intervening in turn the circuit , taking from some near by point of the chassis (0V). That which must be watched is that the Relay RL1 is of good quality.
