[DML] Re: Headlight switch repairs

["David Teitelbaum" <jtrealty@xxxxxxxxxxxxx>]

The design is probably considered a "success" since it lasted over 25 years! The problem is not only the design (and construction) of the switch but the circuit itself. The switch carries the direct current of the side markers and they are fused AFTER the switch so if there is a short circuit in the marker lights the switch has to carry that whole load BEFORE the fuse will blow. Not the best way to do it. Using relays will reduce the current through the switch reducing the heat and helping the switch last a lot longer. Changing over to L.E.D.'s for the marker lights will also help a lot. Going with halogen type lights will increase the load so if you go that way you really should consider relays for the switch to control. You also should check from time-to-time the marker light sockets. They are prone to corrode and when they do they can cause a high current through the headlight switch.
