title: Change marker icon with matching id
body: <p>I'm trying to change the color of an existing pin. I have 5 pins with id values running from 1-5. can I change the pin if it's say equal to 3. I tried something like the code below but can't quite get what I'm looking for. any help would be great.</p>
  
  <pre><code>if(marker.id == 3){
       this.marker.setIcon(myPin2);
  }
  </code></pre>
