Which pre-2000 set had a mobile crane with lights?
I believe the set you're looking for is the F1 Hauler (item no. 6484-1):



Here are the details:


It was released in 1995.
It's a red-and-white truck for towing Formula 1 cars (and has no support legs).
It has an 8 x 4 x 2.33 9V battery box, which is hidden in the body of the 6-stud-wide truck.
It has a 1 x 4 light bar and a motorized winch driven by a 9V micromotor.
