Patent NL-9401054-A (NL)
Title: Brake-light switch
IPC: H01H35/14
Filed: 1994-06-24
Abstract: Patent application No. 9401011 of 20 June (a brake light 70 cm to the right of the driver) generally allows the brake light of the third and fourth cars in front also to be seen. For this reason, when in a traffic jam it is always possible to have a good view of the second car in front braking. This means that in the traffic jam this second car can take the place of the first car in front. A traffic jam can then contain twice as many cars, and the traffic flow can be doubled! A greater distance between cars will only be required at certain bends and flyovers. However, there is a risk that in the event of a frontal collision in a traffic jam the brake signal will not operate, due to the short distance between the cars. For this reason, the invention has discovered a rocker switch with a weighted arm, in such a manner that in the event of a collision the third brake light is switched on.
