make image appear to glow brighter then dim

I have a customer make a strange request (for me, at least). He wants an image
of a light bulb to appear brighter then dim, then brighten again. Not really a
pulsing light, more like a power surge effect. Would anyone know how I could
accomplish this? Thanks!

What makes a light bulb look brighter is that the light becomes more
white/less yellow, it's more difficult to make out detail, and the glow around
it is bigger. If you can make two light bulb images with these differences,
especially if the image of the brighter one can be made by, say, adding a fuzzy
white or pale yellow ellipse with a radial opacity gradient, then you can use
these images to make an animation.

Here's a method to experiment with.
