The stainless steel bezel, strobe and SOS functionality as well as the on-body dual switch system make the TK75 a trustworthy carry on search, caving and scouting missions. Mounted on a vehicle or stowed for emergency use, this light captures the proven performance found in every Fenix lighting product.
