Thankyou to all the experienced night riders who have contributed to this discussion. Here's my distillation of the information that has been offered, and keep the suggestions coming. I will amend this list to keep it up to date.
Bike EquipmentInstall appropriate lights on the bike (lots of threads on this topic)
Use grip heaters if you ride in cold conditions
Fit “Shoo Roos” if you believe in them
Use reflective material on the bike
Use a SPOT to enable others to monitor your journey
Consider carrying the SPOT on your person rather than bike mounted, for better access to SOS in case of an "off".
If you can afford it, use IR night vision
Rider EquipmentWear a high visibility vest
Carry a damp cloth to wipe away bug splats
Yellow glasses don't work, but wear clear glasses under the visor
Keep a torch in your pocket where you can find it easily
Use lubricating eye drops
Keep warm, with Heated Vest, Gloves, Grip heaters etc
Rider Skills, Attitude & PracticesTreat all road imperfections as a hazard, as pothole depth is impossible to judge, so use caution
Night speed would normally be dependant on location, weather, animal life, road conditions etc and not necessarily speed limit
Research and be aware of distances of vision and reaction times whilst riding
Practice quickly using High/Low beam
Listen to your body regarding fatigue and heed the messages
Have your eyesight checked
Ensure someone knows where you are going
Regularly move your head and look to each side to break target fixation
Constantly assess and reassess all aspects of your situation
Constantly look for escape routes
Slow for anything that is unidentified
Don't ride behind trucks
Look to the left as on coming vehicles approach, to minimise glare & recovery from glare
Ride the centreline if there's no traffic
Constantly scan the roadsides
The roo you don't see coming from the side is the one that will get you, not the one you see well ahead in your headlights
If you see a roo, look where it came from for the others
Be aware that animals can be unpredictable
Don't brake if an impact is imminent, but look ahead and ride straight
