Congratulations. I would advise taking it out of its shed and taking it for a run. I run my Dragonfly on 6v. I have a 6v 35/35w halogen headlamp bulb (Classic Bike Shop) and a 6v20w halogen pilot light (Paul Goff). They are not going to blind anyone and I wouldn't intentionally set off on a night time ride but they are fine to get home if it gets dark while I'm out. At Dragonfly speeds the light is OK, the main problem is oncoming headlights which, when your eyes are adjusted to the 6v glimmer, are rather blinding. The pilot light is actually quite good and I have used it when the headlamp bulb wasn't working. It needs a new bulb holder assembly.
I have an LED BA9 bulb for the speedometer which gives a good light.
The tail/ stop is also LED but I have never been really happy with it. The stop is bright, the tail is bright but with the tail light on the brake light doesn't really show up. But the brake light always live. If it remains on when I leave the bike, which has happened a few times, the LED doesn't drain the battery. And the answer to that is a battery isolation switch, and that is the next thing to attend to.
