Hi Yamaha77,
oh yes, contrast is there for sure.
Most likely the red & black wires are for the rear light and brake light bulb filaments and the manufacturers are leaving the ground wire up to you.
You'll have to attach a ground wire to the lamp casing, (a ring terminal under one of the bolts that hold the lamp body to the mounting shell should work)
Because almost all modern bikes (later than a 1960s Britbike, that is) have rubber mounted fenders.
Check if it's the red wire or the black wire that powers the brake light and put rubber washers under the plain washers on the fender's inside as well as the rubber sheet on the outside when you bolt the rearlight in place.
Nice upstate house. "Thou shalt not covet - - - ". It tells me that in the Bible.
Well Im NOT going to put the light on the XS but I AM going to put it on my Honda 750. So this information is still quite useful! Thanks!!
