Can you use halogen in older cars for headlight bulbs?

Halogen headlights can be used in older cars as long as the car's electrical system can support the increased power draw of halogen bulbs. Halogen bulbs typically draw more power than traditional incandescent bulbs, so it's important to ensure that the car's electrical system can handle the additional load. Additionally, the car's headlights may need to be modified in order to accommodate the new halogen bulbs. It is recommended to consult with a qualified mechanic or automotive electrician before installing halogen bulbs in an older car.
