How do I turn on edge highlighting for a part?

[JoePatrick1]

(this has also been posted in the 'The official unoffical "help a fellow plugin developer" thread' for visibility) 

So I'm trying to turn on edge highlighting on a part when it's hovered over in a list (as shown in the screenshots) and I sort of have it working but not completely. When you hover over a part normally and it highlights green, it has very bright edge highlighting and can be seen through objects but if you look at what it looks like when I turn on the highlight with my plugin, it is like the old highlight method which is not as bright and not really visible through objects.

Here is the relevant code and some screenshots

if (hovercheck.Contains(Event.current.mousePosition))
{
	part.SetHighlightColor(Color.cyan);
	part.SetHighlight(true, false);
	part.highlightType = Part.HighlightType.AlwaysOn;
	part.gameObject.GetComponent<ExplosionDetector>().highlightPart = true;      
}
else if (part.gameObject.GetComponent<ExplosionDetector>().highlightPart == true)
{
	part.SetHighlightColor(Part.defaultHighlightPart);
	part.SetHighlight(false, false);
	part.highlightType = Part.HighlightType.OnMouseOver;
	part.gameObject.GetComponent<ExplosionDetector>().highlightPart = false;
}

Here is what it looks like when you hover over the part

Here is what my plugin looks like

Thanks
