Is there a way to emit lit particles?

Hey there :) I've created a particle emitter and set everyt$$anonymous$$ng to "make it snow". However, my level takes place during night and all snowflakes are ugly and all w$$anonymous$$te even when in complete dark. I've tried all shaders in the "Particles" folder, but none of them produces the realistic effect I want - to make the snowflakes lit only when a real light reflects off them (so you can see them faintly in the dark, but when you turn on your flashlight, they become lit and very reflective in that lit area like in real life). I thought it would be possible to ac$$anonymous$$eve with the "Transparent/VertexLit" shader, but it doesn't seem to work on particles (I can't see them at all with that shader). Is there a way to ac$$anonymous$$eve the effect I'm after? A help would be very appreciated! Thank you! :)
