Found a good match for replacement LED's after some trial.
I ended up trying a number of grain of wheat bulbs. Some were not bright enough, some were too large to fit in the hole (even though they said they were 5mm). Others that had a current draw of100mA or 95mA became too hot to touch after a few seconds which worried me a bit (btw.. once I took out the stock ones, even those got pretty warm). I didn't want them too close to the plastic backing of the display, so I figured to go the LED route and tried an assortment of LEDs (all off EBAY). Many did not diffuse light across the display very well at all even though they were supposed to be wide angle.
The ones worked well as far as coloring and even brightness were 5mm diffused warm white (see links below). I found you can't just replace one or two with LED, but should replace them all as the color of LEDs is slightly different.
Also, I used a 510 ohm resistor (I wanted to use 500ohm, but only had 510 ohm at hand) in series to limit the current to the LED.. so we'll see how it goes.
This is what they look like: Using 5mm Warm White Diffused LED
This is the EBAY link where I got them from: EBAY
btw, I noticed that the solder used for the existing grain of wheat lamps appears to be no lead solder, so if others attempt to do this replacement, you'll need a bit more heat to melt the solder. I used solder wick to remove the existing solder before using lead solder on the LED leads.
