1. A discharging signalling system of at least one dispenser of a vehicle, comprising: an indicator arranged to indicate that dispensing is allowed, wherein the indicator comprises a dynamic signal generator arranged to generate a dynamic safety signal when discharging is allowed, wherein the indicator further comprises a first static signal generator arranged to generate a static safety signal when sensors in the vehicle fulfill at least one predetermined requirement,an activation circuit arranged to discharge the dispenser, the activation circuit comprising a first safety arrangement arranged to be activated when an indication from the indicator indicates that dispensing is allowed, the activation circuit further comprising a second safety arrangement arranged to be activated when a discharge of the dispenser is indicated, anda safety processor arranged to generate a safety signal when the safety processor receives the static signal transmitted from the static signal generator and the dynamic signal, wherein the safety signal is configured to activate the first safety arrangement of the activation circuit as long as the safety signal is activated, and wherein the safety processor comprises a timer adapted to control the time length of the safety signal. 2. The system according to claim 1, further comprising: a loop back from the activation circuit to the safety processor resetting the timer of the system when the activation circuit is activated. 3. The system according to claim 1, wherein the indicator is arranged to simultaneously indicate discharging of the dispenser. 4. The system according to claim 3, wherein the indicator comprises a release button. 5. The signalling system according to claim 1, further comprising: an activating processor, wherein the static safety signal is to be transferred into the activating processor, and the dynamic safety signal is to be transferred to the activating processor, wherein the activating processor is arranged to activate the activating circuit discharging of the dispenser when safety signal is true. 6. The signalling system according to claim 5, wherein the activating processor is arranged to generate an activating signal arranged to activate the second safety arrangement of the activation circuit arranged to activate the discharge of the dispenser. 7. The signalling system according to claim 5, wherein the activating processor is arranged to execute a program of discharging dispensers generating a sequence of activation signals. 8. The signalling system according to claim 1, wherein the first safety arrangement comprises a switch and the second safety arrangement comprises a switch arranged to close the activating circuit when activated and thereby discharging the dispenser. 9. A method for discharging a dispenser in a dispensing system of a vehicle wherein the dispensing system comprises a power fed activating circuit, the method comprising: indicating that discharging is allowed, wherein indicating that discharging is allowed comprises generating a dynamic safety signal,fulfilling at least one requirement of a condition of the vehicle, andgenerating a static safety signal;activating a first safety arrangement of the activating circuit when it is indicated by a indication that discharging is allowed, wherein activating the first safety arrangement comprises generating a third safety signal in a safety processor of the system when the dynamic safety signal and the static signal are received at the safety processor, wherein the safety signal activates the first safety arrangement, and wherein the third safety signal is activated over a time controlled by a timer in the safety processor, and wherein the timer is set off when the safety and the static signal is received at the safety processor; andactivating a second safety arrangement of the activating circuit when discharging is indicated, wherein the activating circuit is closed and the dispenser is discharged. 10. The method according to claim 9, further comprising: reloading the timer when a discharge of the dispenser has been made. 11. The method according to claim 9, wherein the indication of allowing a discharge also indicates an initiation of discharge of a dispenser generating an activation signal in a second processor when the static safety signal and the dynamic safety signal are received at the second processor, wherein the activation signal is activating the second safety arrangement of the activation circuit of the dispensing system. 12. The method according to claim 9, wherein activating safety arrangements comprises activating a safety switch in the activating circuit.
