In that case, the only solution I can think of is to morph from the lamp
with the grey bulb to the lamp with the yellow bulb...this will require a
good bit of RAM though because I'm sure you have the lamp heavily
subdivided, but it will work...just be sure to turn on Morph Surfaces.

I just thought of another way to do this, but it's a little weird...make
the surface of your bulb have a yellow color but apply an image sequence
to the Diffusity and/or Luminosity textures so that when you need the
bulb to be grey, the image sequence should be very dark, and when you
need the bulb to turn bright yellow, the image sequence should be solid
white.  You could do this with only two images in the image sequence...
image.001 would be dark grey and image.002 would be solid white...then
set the frame offset value for this image sequence to something that
would make the bulb "snap on" at the appropriate frame.  For example, if
the bulb needed to be turned on at frame 600 in your animation, you'd
change the frame offset to -598.

Please note that in order for frames 0-598 to render correctly, you would
need to do a render at frame 599 first in order to load image.001 into
memory...LightWave will then use this image for rendering until it
reaches the point where it should load image.002.

Does any of this make sense?  I'm half-asleep right now...
