This 2018 Nissan Maxima 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 a headlight, interior bulb, or exterior marker light, this page organizes the fitment details by location for faster checking.
The 2018 Nissan Maxima uses a mix of LED and halogen bulb types depending on the lamp position and equipment level. Because trim and lighting package can vary, it is important to confirm the exact bulb type for your specific Maxima before ordering replacements.
For best results, compare the bulb chart with the bulb already installed in your car, especially if your Maxima has an LED lighting package or has been modified with aftermarket parts. Some positions use LED assemblies, while others use replaceable bulbs such as H11, H9, 7440, 7444NA, 921, 194/7441, 2825/98, 2721, 158, 168/917, and 7440R. If you are converting from halogen to LED, check fitment, connector style, beam pattern, and local lighting rules before purchasing. Small trim and market differences can affect the correct bulb choice, so verifying the installed bulb is always the safest step.
