I managed to do it, but I don't think I can explain it well. Use the LabVIEW help index to find "customizing, parts of indicators (how-to)". It steps you through a lot of it. The way I did it was to place a boolean indicator LED and a decoration of the appropriate shape (e.g. an up-pointing triangle), copy the decoration, and "import image" into the LED. The necessary steps include right-clicking the LED and choosing Advanced->Customize from the popup menu, and clicking the "Change to Customize Mode" wrench icon. I think I ended up importing the image into both the on and off states of the LED, and I had to change the color using the Properties menu.

I'm sorry if this is too vague, but I'm definitely not thinking clearly enough to give a step-by-step recipe this late at night.
