OMG I have wanted to do that...for a LONG time too. I have a Serenity model (yes there's a point here) and when the effects are engaged, the engine in it does the same thing, it lights in a medium level of yellow light then flashes in the same color but much brighter. The effect on this model is exactly what we need, but in green. I know this is really no help, but I know it can be done...
