The problem was presented as the need for a cus- tomer to replace the ever increasing weight and com- plexity of the cabling for~the automotive steering column with a light weight simple method. This also needed to be done in a manner that was cost competitive with the current method of using copper wires to transmit all electrical signals. and detector pair. Again no physical connection is made to the turn signal lever arm. This method uses thm holes in the lever arm to transmit the light from the input fiber to the output fiber. The way of differentiating left from right is through the use of an attenuating material placed in one of the thou holes. This provides a signal level difference at the detector which can be used to indicate the right or let? turn signal needs to be actuated.
