Description

Title: @ ot-green changeover for vehicle taillights Application area: The invention relates to the Hz tail lighting. With the elimination of the rear light should be an optical contrast between colored light by means of a @ ot-green changeover (green) and brake and parking lights (red) are created. 1 Purpose: In particular about the risk of rear-end collisions at night in dicaten traffic, when driving in a convoy or in the case of other bad misunderstandings in which the vehicle lights is switched on, a -at least for one of the following is recommended Vehicle visible - use of contrast colors for a driving light on the one hand and a brake and parking light on the other hand.

1 La @ t A @ AC- @ otorwelt, Meft 4 / April 1971, p. 28, is from the Trier Ophthalmologist Hans Spiecker gave the signal color blue the Vorzu @ vo @ Vot, with the Reason, "that there are practically no 'Bla @ blinden' among the precautionary participants, on the other hand there are very many people whose sense of color is disturbed in the 'red-green area' is. "Accordingly, it would have to be checked whether the possibility in terms of traffic engineering exists, the Kfz-Bre @ sicht generally on Bla @ @ mz @ st @ llen. However, since it is not the goal the invention is to make an optimal choice of colors, should be here from the imStra-Benverkehr @ the usual use of the signal colors @ot and green.

State of the art with criticism: Is has been common so far, the bilateral Two-color tail lighting (e.g. of a PFW), namely yellow for the direction indicator and red for brake and tail lights, regardless of the different types Meaning of the latter. Some models even have the rear lenses red for @ie @ahrtricht advert, while other older models still have two-circuit systems exist in which the yellow direction indicator is also the brake light. - Purch dies @ n @insstz of various makes and @ usführ @ n @ en of chluß-, @ link- and Bre @ slichtkombination @ n with s.T. de @ tlich divergent @ end @elligkeitswerte comes it is frequent - especially with the difficult traffic conditions listed above to false reactions of the following drivers, be it that the area light of the sfa The vehicle is recognized too late or its tail light is changed.

Task: The invention has the task of reducing the risk of accidents, by eliminating such mix-ups and incorrect reactions: by the A change from running light to red brake light will result in a braking delay marked. benso it is at the same time as a candlestick (only with c @ alteter Vehicle lighting) functioning light is suitable, hold @ e vehicles - especially in so-called flowing traffic, such as in front of traffic lights or during traffic jams - to display.

Solution: According to the invention, this object is achieved in that --- a) In addition to the brake light switch, a second switch is installed, which is used with the Pressing the @ ußbre @ shebel turns off and on when you let go of it, --- b) the red lens for the taillights has been replaced by a green one for the driving lights and --- c) an additional switch, initially designed as a Tachowellon switch is installed, through which the red-green switching takes place.

--- d) The required additional electrical installation is different Circuit diagram visible.

(BLS - brake light switch, @GS - @ ot-green switch, LS - light switch, LS - ignition switch) Description of an exemplary embodiment: An exemplary embodiment the invention is shown in the drawing. The function of the phot green switch is made clear by the circuit diagram. It is when the @ ahr @ euglight is switched off interrupted.
