Mechanic's Note: Headlight bulbs are often the first casualty of a failing voltage regulator. Installation Tip: Never touch the glass of the new bulb with your bare fingers; skin oils can cause "hot spots" that lead to premature bulb failure. Pro Tip: If your bulbs are constantly blowing, check your Voltage Regulator to ensure your system isn't overcharging!
