This clock has sentimental value for a customer...I know it is not a hot collectible, but for her it is important. The problem is that the light bulb is failing. This model (Dialite) had...go figure...a lighted dial! I have provided a photo of the current bulb. It seems to me this is a later replacement...probably not the original bulb. I could get a parts clock to replace the missing bulb base and put a new bulb in, or I could put in an LED bulb. Any thoughts on this? If I do put in an LED, anyone have a recommended bulb and source? Thanks!!!
