If it makes you feel any better about it, I'd argue that you are far better served by a steady light than a blinking one. I like steady lights for visibility, not blinking ones. Blinking ones are pretty annoying, and surprisingly difficult to gauge distance. They make you 'visible', but cars have very little depth perception with a blinking light, so while they can see you, they can't really tell where you are, which is a problem.

We did a bunch of tests at my bike club, and overwhelmingly, people favored the steady lights after seeing them in a comparison test, including die-hard pro-blinky people.

So, maybe just keep it on solid?
