Have them on my bike and my wife's Deluxe and never turn them off. Don't really think it matters much on battery life. My bike is four years old and still on the original battery. (knock on wood)
I run mine all the time, never turn them off. They sure are nice at night on the long winding country roads I ride to get home. I doubt if the battery is affected one way or the other.
Turning off the lights will not effect battery life at all........If you really are worried about battery life get your self a battery tender and hook it up every time you park your bike in the garage. It will keep your battery at full charge.....comes with a quick disconnect and will not boil the battery.......I have one on my bike, my tractor, my dump trailer battery and my old pickup.
Keep your lights ON .If you have them use them. they dont effect the life of the battery but most of all its safer.even if it cut into the battery life you should keep them on because most important your dealing with your own life and thats more important then battery life............................
The battery life is unaffected by the lights for the simple reason that except for the few seconds before the engine starts. The lights don't run off the battery at all. They are supplied power from the generator/charging circuit just like all of the electrical devices on the bike.
If I had them I would never turn them off. Like jokr said, even if it did affect overall battery lifespan. The cost of it lasting a month or so less is well worth the price if you can be seen that much sooner/more often.
I always ride with them on, more lights the better on the front and rear. Battery life is not affected, besides, your safety is more important. Keep them on
