Yes, the AA Zebralight SC52 fits in the P3 with the 1 1/4" tubes. It will not fit all the way in the 1" tubes of the P3MT. You can see the Zebralight in the P3 in my 1st post in this thread, which I think is post #910. The Fenix E12 and Thrunite T10 II both fit into the 1" tubes of the P3MT. I'm guessing most tail click AA lights that are not bulky will fit in the P3MT. I do not know if the Skinth team has any variance in manufacturing, but I imagine not enough to make a difference here.
