Whatever else may be wrong with the loom, they certainly gave you enough length; my wires are barely long enough to get into the headlight bucket!

It was as long on the other end, I had to pull it up a bit into the headlight to get the many connections correct behind the side panel. Will have to shorten some of the cables or I won't get the headlight in. Usual pattern parts, they appear to go to a lot of trouble to get it wrong. Bewildering really, it's as easy to get it right as wrong.

The brown/white is for the small park light, which is not fitted in US but is actualy a legal requirement in UK as according to construction and use/mot it is an obligatory light, unlike the headlamp which doesnt have to be there but if it is it must work.

That means then that the front parking light will be on whenever the rear light is on, ie when riding at night. That can't be right?

Every vehicle I have owned has the front side lamp illuminated when the rear lamp is on including when the headlamp is on dip or main. I believe the law calls them positional lamps.
Only DTRL's have changed that slightly - some dim at night etc.

Agree with Ted, they are designed to have the side light lit whenever any lights are shown, including as Ted says dip and main.

Fair point. If only I had a side light.

The brown white IS for the front parking light but the yanks use sealed beam headlamps without one .
The orange/white and blue/white are for the front running light in the US front indicators, not legal in UK so leave them loose
