Classic/Antique Car Repair: 66 mustang headlight, radiator core, high beams

Question
hi, I have just recently gotten my mustang running and ready to drive but as soon as i got it ready i noticed that the passenger headlight wont work and i cant switch it to high beams i was wondering what i needed to replace

Answer
have you changed the bulb? If so and it still does not work check the ground for the headlight. It should be grounded to the radiator core support on the right side of the car. Make sure it is a good tight clean ground and see what happens. if this does not fix it let me know and we will go to the next step.
