Hi Edward,
Mine often last for years. As an alternative, have you considered an electric space heater turned on low? I have used these with success. I normally suspend these horizontally and tape the tip switch if there is one. Of course, experiment with it to be sure you are getting the right height and temp.
If there is one thing the Wizard of Oz has taught me, it is not to trust school teachers on bicycles.
