On my 650D I just found a weird issue. Low beam works perfectly, but when switching to high beam, low beam stays on, however the light goes a bit dim. I guess due to the increased voltage drop when both filaments are drawing current. My dimmer switch seems to be a correct European 77 model, with only 3 wires to it. (7 wires total to the entire LH switch assy.)
Both the slider and stationary part seem to have the necessary contacts for a US market switc, I.e 2 switches in 1.
The one that is connected seems to be of a " make before break" design, so both lights are on for a brief moment during switching. Which is generally a good thing. Except that my switch does not disconnect low beam when high beam is on.
Is it possible I have an incorrect slider, or is it just a case of manufacturing tolerances?
The only solution I can see, is to file a bit off one end of the switch plate, and somehow extend the other end, to ensure the low beam disconnects when switching to hi beam. Is there any other fixes? I am definitely open for suggestions here!
