Bulb size chart
This 2014 Buick LaCrosse bulb size guide helps you verify the correct bulbs by lighting position, so you can match the right part before you buy. Whether you are replacing an exterior lamp or a small interior bulb, the chart is organized to make fitment checks easier for the front, rear, and cabin lighting on the 2014 Buick LaCrosse.
Because trim and lighting package can vary by market and body style, the exact bulb type may depend on how your LaCrosse is equipped. This page focuses on the listed bulb positions for the 2014 Buick LaCrosse and gives you a practical starting point for finding the right replacement bulb for each location.
For best results, confirm whether your car has halogen headlights or HID headlights before ordering, since the headlight, daytime running light, and front side marker bulb sizes differ between those setups. LED exterior bulbs and aftermarket conversions can also change the fitment or light output, so it is smart to compare the installed bulb and connector style before purchase. If a bulb has been replaced in the past, the current part may not match the original equipment listing, so checking the actual bulb in the vehicle is the safest way to avoid a mismatch.
