I use red or black incandescent bulbs for some of my snakes at night- mine are substantially dimmed* mostly because they put out a lot of heat, rather than for the amount of light- which doesn't appear to bother them- in fact some clearly enjoy the warmth from above. These lights are visible to them, but not all that bright. I'd say go ahead, it's fine- just make sure you connect it to a lamp dimmer (aka "rheostat")- any hardware store has them, not expensive. You can buy a dimmer switch installed in an extension cord- very convenient.
