Topic The comfort of road traffic in order with to raise security, being available, rather than regarding the braking and acceleration of the transport vehicle, it is something which offers the appropriate indicator.SolutionsThe accelerating change meter (jerking), the electric light source above the change vessel and 1 groups is included in the indicator. While braking, the jerking meter sending the signal to the change vessel, in order to make the visible photoeffect cause which operates in all directions changes the braking indicating lamp. From this visible effect of the extent whose braking is strong is prominent. With this manner, visible it is quickly perceived to the eye of the human very (angle) augmentation of size can be done simulation. To similar, in order to make the photoeffect cause which acceleration indicatory light approaches mutually during acceleration of the transport vehicle, it is changed. This device is autonomous, as for joint with the transport vehicle device when altogether it is unnecessary, simultaneously, loading is possible in the optional transport vehicle the individual case and general-purpose installation tools and with the individual power source.
