Narrative:
During enroute climb I detected that my head was actually getting hot from the cockpit dome light. I immediately selected it off; this did not shut off the light. [I] called maintenance from my personal phone who patched in with gulfstream to determine how to shut it off. [I] attempted air stair dome light switch; which also failed to extinguish the light. By this time the light was beginning to overheat to the point of discoloration. It was then suggested I attempt to find a circuit breaker (circuit breaker); to isolate the light. Circuit breaker recommendations from maintenance were not successful. Then I pulled the air stair light circuit breaker and the dome light went out. Continued to intermediate stop; and requested an aircraft change; which was honored.
