Toyota Repair: headlights, toyotta, battery voltage

Question
What is the most voltage that I can put on my toyotta corolla 1.6 gsi 1995 model headlights

Answer
The headlights are designed to work with battery voltage of 12 volts , the alternator can put out 14.8 volts, so about 15 volts can be applied keep in mind that higher voltages will decrease bulb life and. For example 24 volts would cause the light to be twice as bright but it may burn out shortly due to too much current being drawn.
