Chevrolet Malibu 2018 Bulb Size
Bulb size chart
The 2018 Chevrolet Malibu uses different bulb types depending on the lighting position, trim, and whether the car has LED tail lights. This page helps you verify bulb sizes by lighting position so you can match the correct replacement before you buy. It is especially useful when you need to compare front, rear, interior, and cargo-area bulbs on the same model year.
For the 2018 Malibu, some exterior lamps are LED assemblies while others use replaceable bulbs such as 9005, 921, 7444NA, 7443, and 7443R. Interior and convenience lights may also use different sizes, including 2825/98, 194, 7441, and 7065. Checking the bulb by location is the easiest way to avoid ordering the wrong part.
Fitment can vary by trim, lighting package, market, and body style, so always confirm what is installed on your specific Malibu before purchasing replacements. This matters even more when comparing halogen and LED setups, because some versions use sealed LED units while others use serviceable bulbs. If you are considering aftermarket LED conversions, make sure the bulb base, socket depth, and beam pattern are compatible with the housing. The safest approach is to inspect the old bulb, compare it to the chart, and verify the part number or base style before you order.
