Once you're alert and your bike is ready to ride, you can make yourself easier to spot by wearing high-visibility gear, putting brighter bulbs in your headlights or sticking a louder exhaust on your ride, but these steps still rely on someone else being more careful with your life than you are.
After that, all that's left is your gear to keep you alive. Thanks to Cairns you'll be wearing a lid. You might even have a jacket and gloves, if you value your skin. But it makes sense to get all the armour you can afford and bear to wear.
Several types of rider airbags are available from waistcoats, such as the Spidi DPS Neck and Dainese D-air Street, for several hundred dollars, to jackets and one-piece racing suits, such as Alpinestar's Techair, which costs thousands.
Hopefully these precautions will keep you riding for as long as you want to, but if you do get into a serious scrape the speed with which help reaches you is critical to your chances. What if you're alone, on a quiet street late at night, or blasting down a country lane and no one's there to notice?
One last piece of kit you'll probably have with you is a phone. Now it could end up saving your life, even if you're too injured to use it.
The RealRider social network has developed an app that uses a smartphone's tilt and rotation sensors to tell if you've had an accident.
It sends an alert to your phone, and if you don't or can't cancel it, it contacts emergency services, who will dispatch an ambulance to your location using the phone's GPS co-ordinates.
Like Cairn's work, the real genius is in taking something we already have and putting it to a new use, making it safer to enjoy two wheels without robbing it of any excitement or costing a fortune.
It won't save you from your own or others' stupidity, it won't stop you getting hurt, but if you do get into an accident where you can't pick yourself up again, it could be what lets you live to ride another day.
