There is a few different ways. One way is use like a dryer vent that has a closing flap. When the fan shuts off the flap will shut and light will be blocked. Another way is used 90 degree bends. Get dryer vent tubing and bend it at a 90 and hook ur fan up to that. Most of the time 1 90 degree bend will kill the light.

alright ill try that idea. so if i put like a piece of cardboard like half way infront of my fan and a bit further another for the other side of the fan it will block light and let the air flow? i just want to make sure i got everything straight before i do it. and that is a great idea thanks. =)
