Hello all im not 100% sure if this is were this post should b but i have the fenix tk11 and dereelight dbs v3 and ive seen headband straps but my lights dont fit the ones ive seen. Id love one that could hold both lights it would b real handy in some situations ie fishing or camping when i need my hands for something else. they both take 18650 batterys so does any1 know of any headband straps that would accomodate my lights ?
