Repairing Lucas Light Switches

Repairing Lucas Light Switches

Many of us owners/drivers of LBCs have had a problem or two with the Lucas light switch found on most any dash that malfunctions.  I took mine apart to see why I only had working headlights and no markers or parking lights.  The turn signals as well as the hazard lights worked perfectly, so I knew that I had proper power.  After I cleaned the brass contacts on the switch as well as the slider, I still didn’t have the markers working.  It was dark when I brought the dismantled switch into the house.  During this short trip, I lost the small spring and couldn’t find it. What to do?!  My son suggested that maybe a spring from a retractable ball point pen would work.  Great suggestion!!  The spring was the perfect diameter and after cutting of several turns for length, I put it into the switch.  The switch was once again operable in all positions.  I attributed my problem to a rusty spring that had lost its tensile.  Simple repair without any cost!!
