I did that that too, just didn't post pictures because the little squares,on the back side of the reflector, make the shape of the "LS" look bad. Best bet would be how andrizzle was saying, cut LS into the reflector and have LED's light it up, seems like it would look cleaner.
Either way, I think I might black out my reflector. Either paint it black or maybe tint. I dont think those little LED's do much so nothing would really be los it I paint the reflector black
