OK now the marker lights are getting the LED treatment too!
And to add insult to injury we are going with a 2 LED assembly.......(double blasphemy! two lights where there should be only one!)
Here is what I used. $4.99 ea (yeah I know......do I have stock in that company?)
Nope, this is just a source I found when I was looking. They have a better selection now than when I purchased so you may find something more suitable for your purpose.
