Try your 4 way flashers and walk around car, see if all bulbs are Ok.
Does your brake lights work? And does it go into gear?

Thanks for your answer yes the brake light workig and it goes in to gear

If not a fuse, it should be traced to headlight switch. Do you have a plug at the back of the vehicle for towing?
