Digital thermometer and more consistent heat.

The little plastic strips are terrible for measuring temps. Also, since heat rises, temps should be measured at the ground level where the snake lives.

Lamps are fine if you want to use them, but you can't leave them on 24 hours a day or they will stress your snake. But when you turn them off at night, the temps in the cage drop. Using a red bulb or a ceramic bulb will keep the cage the same temp 24 hours a day which is better for your snake. Or, you could just switch to UTH's.
