Off/On/Mom switch replaces the standard rotary action rear wash wipe switch in the Defender. The internal switch wiring is configured so that it retains the wiper park function when the switch is turned off. Switch is supplied with a RWW legend on rocker. Please note the narrow 'on' orange LED does not illuminate when switch is 'on.'  We have retained the narrow bar for aesthetics so that the RWW switch matches your existing carling install. The square window with legend illuminates Green with sidelights.
