During takeoff; I; the Captain; PM; saw a very bright single white LED light on center-line at the far end of Runway 35R. The light could be interpreted as the taxi light of another aircraft lined up on the opposite end of our runway. I was confused because I didn't hear another aircraft on Tower frequency at that time. I thought it was a visual illustration caused by a light source outside the airport's perimeter. Since we were very light with just 12;000 LBS of fuel for our flight to ZZZ; I thought we could get airborne with less than 1/2 of the 13;500 feet runway used. I elected to continue to takeoff. The FO also saw the light and he didn't know what it was either; but we did not discuss the light during takeoff roll. I didn't want to distract him during this critical phase of flight; since I decided to continue the takeoff anyway. We discussed it at altitude and I told him I would submit this report about the light distraction.
Air Carrier Captain reported a distracting light at the opposite end of the runway during the takeoff roll in COS.
