Indicator Switch Mini Mk2 & Leyland. This switch is for horn button, indicators and headlight (high and low), plus headlight flash.
Workshop advice.
It is always advisable to Fit and wire Headlight Hi and Low beam relays to the two circuits to prevent overloading Switches. This also give the vehicle much improved light brightnness as it gets rid of the Voltage drop which is normally present in original headlight wiring. Also advisable to add a horn relay especially if using non factory horns.
