If cleared to depart from the runway, I will proceed through red illuminated Takeoff Hold Lights.

I interpret Takeoff Hold Lights turning off as clearance to take off.

* I have observed Takeoff Hold Lights at DFW turn on in response to traffic in the following locations:

	East side
	West side
	Both East and West sides
	I have not observed THLs at DFW
