Narrative:

Following departure; at about 3;000 ft; [I noticed] a burning smell followed by smoke coming out from under the circuit breakers. I notified approach of the issue and requested permission to land immediately at the nearest airport. Approach approved request to land at an air force base which was 3 miles to the north. I was asked to switch to tower and they quickly cleared landing and would have emergency personnel assist. Emergency procedures implemented followed by a good landing and we stopped the plane at the first turn off. The plane was vacated and fire personnel inspected. A melted wire leading to the landing light had shorted and melted in two pieces. Due to the quick response; no damage was done to the aircraft other than smoke smell. Air force incident paperwork was completed; mechanics consulted and determined that the aircraft was airworthy; followed by a departure about 1 hour later. The aircraft is now at a mechanic and avionic shop for repairs. The staff and support team at [the air force base] were very understanding and courteous.
