Narrative:
Departed from the gate and completed before takeoff checklist. When the throttles were advanced for takeoff the takeoff warning horn sounded. Aborted takeoff (20 KTS) and cleared the runway. Elevator trim was in the green, flaps 5, and speed brake reset so we recycled the flaps. During flap recycle, noticed no transit light or overhead leading edge annunciator lights. Recycled leading edge flap position indicator circuit breaker. Annunciator lights now worked normally with flaps. Reset flaps to 5 and continued to den. Circuit breaker for leading edge devices is one our company has us pull when aircraft sits overnight. These breakers tend to be intermittent more often than the others.

Title: THE TKOF WARNING HORN SOUNDED ON TKOF, ABORTED, RECYCLED FLAPS NO TRANSIT LIGHT OR LEADING EDGE ANNUNCIATOR LIGHTS. RESET LEADING EDGE CIRCUIT BREAKER. RECYCLED FLAPS, LIGHTS NORMAL, AND TKOF NORMAL. TKOF ABORTED.
Narrative: DEPARTED FROM THE GATE AND COMPLETED BEFORE TKOF CHKLIST. WHEN THE THROTTLES WERE ADVANCED FOR TKOF THE TKOF WARNING HORN SOUNDED. ABORTED TKOF (20 KTS) AND CLRED THE RWY. ELEVATOR TRIM WAS IN THE GREEN, FLAPS 5, AND SPD BRAKE RESET SO WE RECYCLED THE FLAPS. DURING FLAP RECYCLE, NOTICED NO TRANSIT LIGHT OR OVERHEAD LEADING EDGE ANNUNCIATOR LIGHTS. RECYCLED LEADING EDGE FLAP POS INDICATOR CIRCUIT BREAKER. ANNUNCIATOR LIGHTS NOW WORKED NORMALLY WITH FLAPS. RESET FLAPS TO 5 AND CONTINUED TO DEN. CIRCUIT BREAKER FOR LEADING EDGE DEVICES IS ONE OUR COMPANY HAS US PULL WHEN ACFT SITS OVERNIGHT. THESE BREAKERS TEND TO BE INTERMITTENT MORE OFTEN THAN THE OTHERS.
