I just discovered that my headlights are wired in reverse, high beam on the switch is low beam at the light. I am contemplating just switching the bulbs, but the wire for the bottom light might not reach to the top position. The other option is switching the wires at the switch. I am wondering if anyone has been inside of this switch and has any words of wisdom re: this approach.
Then there is the optical horn to consider......

Hi Spike,

Maybe You can extend the wires.

Change the wires over in the plastic connector from the handlebar switch, not a big job, use a jewellers screwdriver and your specs (if you have to squint for close up work like me these days Cool

I've had the same "issue" with a DB6....but seeing as the lights are always on when the ignition is on....and the high/low facility is just a push button for one or the other...I left it as is

If I were to change it my preference would be at the headlight and not the bar switch......these units are always fiddly and you'll find that the wires will be soldered onto the connecters and thus harder to change around.........

My policy would always be "if it aint broke...dont fix it"....it could be that changing the wires around would also mess with the "flash" facility on the front of the switchgear....on the DB6 i was talking about...this worked fine even though the hi/Lo switch was the wrong way around...

I have been suffering from the respiratory virus from hell so have not done much in the shed. That said, my first preference would be to work at the switch as my career was that of a custom jewelry maker. I have lots of tiny tools and magnifiers, don't cha know. As it stands now, if I use the high beam switch to activate the low beam, triggering the optical horn does nothing. With the high beam on the optical horn trigger activates the low beam.
As soon as I feel a bit better I will open the switch assembly and take a look inside. Looking at the wiring diagram my problem is the color code. I recall seeing what the Italian lettering for the wire colors means but I can't seem to find it now. Does anyone have the key to the wire colors?

Ah...yeh...I see your problem now...the electrical wiring diagram is only abbreviated letters for colours...and presumably its in Italian....

Colours for the dimmer reading left to right are

BI, VE, GI, NE (Bianco, Verde, Giallo, Nero - White, Green, Yellow, Black)

Colours for the flasher again L-R

AZ, B/N, RO (Azzurro, Blue/Nero, Rosso - Light Blue, Blue/Black, Red

Horn is L-R

GR, V/N (Grigio, Verde/Nero - Grey, Black/White)

I hadnt realised that the colours had no code...so have gone to my DB4 electrical diagram...clearly the letters denote Italian colours

So here goes

Nero - Black
Azzurro - Light Blue
Bleu - Blue
Verde - Green
Giallo - Yellow
Rosso - Red
Rosa - Pink
Arancione - Orange
Marrone - Brown
Grigio - Grey
Bianco - White

The above seems to cover all the colours you need if you pick up the first one or two letters of each italian word......Best of luck

No worries Vince.....But there was me thinking that Bimota had improved the quality of their workshop manuals with electronic versions...and full colour photos....yet in the DB5 and DB6 workshop manuals....the wiring diagrams are all in Italian...with no translation...whereas DB1, DB2, DB4 workshop manual wiring Diags are in English codings...with translation into Italian.....A bit one sided for the new manuals and bikes....Ho Hum
