Our aircraft was cleared for takeoff. The First Officer was pilot flying. Normal transfer from me to him. First Officer pushed power up and I did final thrust adjustments and called out 'thrust set'...all systems normal.' After adjusting thrust I looked out at the runway and noticed the red take off hold lights illuminate. I called out reject; took control of the aircraft and did the reject procedure. We were at approximately 80 knots. We called tower; cleared the runway; reviewed the QRC reject checklist and did the brake cooling chart. We went back to the gate to have a brake inspection per the operations manual guidance. I informed tower that the red THL lights had illuminated after we began our roll and Tower said they did not know why. There were no vehicles or aircraft on the runway that would have triggered the lights. I suggested they deactivate the system if that was the case. Good crew coordination with my excellent First Officer. Not sure why the lights illuminated but the runway was clear and they were not on when we began the take off roll.
Air carrier Captain reported a rejected takeoff due to the red runway incursion warning light activating during their takeoff.
