The more motorbike vehicles cause accidents, the easier it will be, for example accidents due to turn signal lights that forget to be activated after being used. Accidents caused by motorcycle riders and accidents caused by no security system on motorcycle vehicles. For this reason, research is done to design an automatic timer to turn off the turn signal. This research was conducted using two NE556N timer ICs by utilizing a capacitor charging system which is regulated by a resistor so that it can produce a stable signal and the signal is unstable. Two output signals from the IC NE556N will be used to set the timer off and set the turn signal to blink. The results of the research that has been tested on CBS 125 Honda vario vehicles in 2013, the deadline for turn signal lights that can be produced by the NE556N IC timer for 71 seconds with the number of turn signal lights 89 times for 1 minute. We can conclude that this tool can work stably and can be applied to CBS 125 vario motors with a 13.6volt voltage
