IFLs in Material definitions

Hi guys,
Can an IFL be used in a TGEA material? I'm trying to create a 2-pass material that's got emissive, blinking lights overlaid on a computer console, but I'm not having much luck with the IFL.

new Material( consoleTest2 )
{
	// STAGE 0
	// metal panel
	//----------------------------
	baseTex[0]  = "panel1";
	bumpTex[0] = "panel1_normal";
	
	// STAGE 1
	// blinking indicator lights
	//----------------------------
	baseTex[1]       = "engLights1.ifl";
	emissive[1]      = true;
};

IFL contents:

engLights1a 7
engLights1b 19
engLights1c 7
engLights1d 3
engLights1e 5

Any ideas what I've done wrong here, if anything?
