think you will find that was for indicators/hazards and was cos the mark 3/4 escorts had no hazard/indicator telltale but you could hear em clicking or similar.after near 40 yrs after production however i stand to be corrected as im now probably as decrepit as the escorts concerned…..the only good escort tended to wear a dress and cost money to take home!the 4 wheeled variety on the other hand rarely made it home at all…..
