Don’t be that person who washes the car but forgets about the all-important (and often grimy) headlights! Mix one cup of distilled white vinegar in one quart of water, and as a mild abrasive (for bugs and other sticky road goo), add one tablespoon of cornstarch. Use a sponge to wash the headlights with the solution, then rinse with plain water. You’ll see the light!
