Replacement bulbs for Moonbeam alarm clocks

The older Moonbeam models have a replaceable light bulb that can be purchased online, here is a link to one of the sources: http://1000bulbs.com/product/76/IN-0010C7DC.html

The new Moonbeam models (ending with X, eg: 43000X, or 43007X) have LED lights and cannot be replaced.
