You definitely need to ditch the red light immediately...I hope that isn't his Basking Light during the day, is it? That's a huge no-no, a bearded dragon needs only a bright-white colored Basking Bulb, as you are trying to replicate natural sunlight over their tanks. A red light confuses night and day for them (they see in full color), and it can also cause severe eye damage if it's on all day long.
If you are using that red light as his daytime Basking Light you need to go and buy either a reptile specialty basking bulb that is bright white in color, or what most of us use are the Halogen Indoor Flood Bulbs like you buy at Lowes, Home Depot, or Tractor Supply. They are cheaper, all are bright white in color. Just get the same wattage that the red bulb is. And throw the red bulb in the garbage.
As far as nighttime, he most likely needs absolutely NO NIGHTTIME HEAT SOURCE AT ALL, and I can guarantee that he's not slept soundly under that red bulb at all.
Here's the deal: They are naturally from the Australian Desert, which is #1) Pitch-Black at night, and #2) Very cool, much colder than it is in the daytime. So you absolutely cannot use ANY TYPE OF LIGHT AT NIGHT OVER HIS TANK. It's disrupting his sleep greatly. And secondly, as long as his tank stays at 65 degrees at night he is very comfortable and needs no nighttime heat source at all.
I live in Central Pennsylvania, just as cold as Michigan is, and I've never once used a nighttime heat source for any of dragons in 15 years, not once. This is because my house at night is at least 60 degrees, as I'm sure your's is, otherwise you're freezing yourself. So as long as your house is kept at least at 60 degrees at night, his tank will be right around 65 degrees, and will be perfect.
If for whatever reason you like to freeze yourself at nighttime and you keep your house at say 55 degrees, and his tank is around 60 degrees, then you are only trying to bump his tank up by 5-10 degrees, and so you need to buy a very, very low wattage Ceramic Heat Emitter (CHE) bulb, like a 10-20 watt CHE at the most. You're using a heat bulb right now that is probably at least a 50 watt bulb, I bet his tank temp at night is over 80 degrees, which is making him very uncomfortable, and then on top of it you've got that red light on. It's unnecessary, and he will sleep so much better and be so much more active during the daytime if you throw out that red bulb, and let no nighttime heat source on at night, then use your digital probe thermometer or temp gun to measure his tan temperature about an hour after you turn off all of his lights. As long as it's 65 degrees or above then he needs no nighttime heat source at all, and he'll be so much better off.
Please, please get him a bright white colored Basking bulb for the daytime immediately, that red bulb is obviously causing him issues. The closest way you can replicate natural sunlight over his tank is to put your UVB tube right alongside a bright white colored basking bulb, both over the Hot Side of the tank, sharing the top of the Hot Side of the tank, then move his basking spot/platform directly underneath both lights, so that he's getting the bright white light, the heat, the UVB, and the UVA light all at the same time. This is what a desert reptile needs.
