After watching the trailer dozens of times, I believe that what Kylo Ren is turning his lightsaber on for is on the left part of the screen of the first few frames we see him. It could be a downed ship or something, but that's what I think it is.
Don't look at this pic to look for it, but watch the trailer a few times and you may begin to see things.
