Buick Regal 2002 Bulb Size
Bulb size chart
If you are replacing bulbs on a 2002 Buick Regal, this page helps you verify the correct bulb size by lighting position instead of guessing from the package. The Regal could use different bulbs depending on trim, market, and body style, so checking the exact location first is the safest way to buy the right replacement.
Use the bulb chart on this page to match each lamp on your car, from the high beam headlight and front turn signal to the dome light, license plate light, and rear brake and tail lamps. That makes it easier to compare the bulb in your vehicle with the listed size before you order parts or start a repair.
Fitment can vary on the 2002 Buick Regal, especially when comparing trim levels, lighting packages, and replacement housings. Halogen bulbs and LED upgrades are not always direct swaps, so make sure the bulb base, shape, and wattage match what your car uses. If you are considering an aftermarket LED or conversion kit, check for beam pattern, polarity, and space inside the housing. The best practice is to inspect the installed bulb before purchase, since a previous owner may have already changed it or a catalog listing may not match the exact equipment on your vehicle.
