1995 Mercedes Benz SL500

As I was driving I turned on the headlights and fuse 1, white 8amp blew. When I replace the fuse and turn to parking or lamps, the fuse blows. I have checked the bulbs that seem to be related to the fuse and unless I missed one, they seem to all be ok. I don't know what could be shorting the circuit. Thanks in advance for helping me.
