I don't have a bulb at all i have a ceramic heat source.I suggest adding second heating bulb.In my experience incubator bulbs go bad at worst times.If you have 2 bulbs you don't have worry about bulb going out on day 17 when nobody is home to notice.With 2 bulbs incubator gets to temp twice as fast and if bulb goes bad you still have other bulb to heat incubator and keep eggs at proper temp.This is especially important if using a fan in incubator.With no heat source fan will cool and kill eggs very quickly.

But i am planning to add a small bulb like an appliance light bulb or something so its easier to watch the hatch.
Thanks for the suggestion!
