I generally take it slowly in the dark for the very reasons you've mentioned.
You could get a bright light (for example, I have this) which will help you see pot holes and make you a bit more visible via a pool of light on the road. Just be sure that you aim the angle of the light as far down as possible so that you don't dazzle other road users.
