Officials say the pair became disoriented in a blinding snowstorm Saturday on Katahdin's treacherous Knife's Edge.
Baxter State Park rangers were alerted to the hikers after seeing headlamps on the Dudley Trail.
According to officials, Ranger Michael Winslow and a volunteer were able to reach the men, leading them to safety at the Chimney Pond Ranger Station. The hikers remained at the station overnight, nursing minor injuries and frostbite.
If they hadn't been wearing the lighted helmets, the outcome could have been entirely different, according to Winslow.
Winslow also warned that winter conditions can change rapidly on Katahdin and in the park and visitors should review the park s website for winter basics.
