[Ducati] ST3 Headlights

[Allen B. Judy]

My 2005 ST3 is like yours Ernie.  They must've changed them since '99.  I 
suspect that the newer lights are brighter than the '99's and draw more 
battery and that's why they changed it.

I own a 2004 ST3. Is there any way to get both the low and high beam on the 
headlight to stay on together for high beam?  I'm looking for more light at 
night and when you switch the two position headlight switch to high beams, 
the low beam lamp goes out and only the high beam lamp comes on, however 
when you have the switch on low beam and press the passing light switch, 
both high and low beams stay on together. I tried positioning the headlight 
switch in between the low and high positions, it worked for a short while, 
unless the switch popped back to one of the detents for low or high. Now my 
high beam won't come on when I move the switch to high. I'm assuming that I 
burnt out the headlight switch?  As the high beam will come on when I press 
the passing light switch. Any ideas? Anyone know if Ducati makes a switch 
for low beam and both lamps on for high beam? Or is there some safe way to 
wire the headlamps to both stay on when the switch is set to high? I don't 
want to burn
anything out or overload the electrics.

Ernie, my ST2 uses both bulbs together for high. That normal for a 1999.
My owners manual says so also. See what the manual says. If that is not
the way a ST3 does it you could look at the schematic in the owners
manual to see what needs to be changed.
