[simpits-tech] controling a 28v circuit with a 5v

[Justin Messenger]

I am using the Simkits multi-controller and have been playing with the 5v LED outputs. The LEDs are cool, (got the marker lights working last night) but I got to thinking, it would be great to use those signals to toggle my 28v bulbs.  There are a couple of places where LED wont work in my sim.
   
  But this exposes my lack of electronic knowledge so my question is,
  what would be the simplest way to toggle a 28v DC circuit with a 5v 20mA DC circuit?
