Automobile Exterior Light Bulbs

Check your vehicle owner's manual or the existing bulb for the specification (e.g., H11, 9005, 1157), verify whether the fixture requires halogen, LED, or HID, and confirm socket fitment and voltage to ensure compatibility

Many LED bulbs are designed as direct replacements for halogen sizes, but you must confirm housing compatibility, heat dissipation, and beam pattern; some LED kits require adapters or may need a CANbus decoder to prevent flicker or error codes

Lifespan varies by technology: halogens often last hundreds to a few thousand hours, LEDs can last several thousand to over ten thousand hours; factors affecting life include heat management, vibration, water exposure, and electrical system stability

Sometimes—LED or HID upgrades may require ballasts, resistors, decoders, or new sockets for proper operation and to prevent hyper-flashing or dashboard errors; consult product notes for required accessories before purchase

Confirm the bulbs meet local vehicle lighting regulations (beam aim, color, and brightness limits), adjust headlight aim after installation if necessary, and avoid colors or intensities prohibited for road use in your jurisdiction

Prices vary by technology and quality: budget halogen replacements are typically the least expensive, while LED and HID conversion kits are higher; shoppers commonly find options ranging from under $50 for basic replacements to higher amounts for premium kits, with this category averaging around the low tens to low hundreds
