Acura MDX 2015 Bulb Size
Bulb size chart
The 2015 Acura MDX uses a mix of LED and replaceable bulb types, so the right fit depends on the exact lighting position on the vehicle. This page helps you verify bulb sizes by lighting position, making it easier to match the correct part for headlights, tail lights, interior lamps, and exterior signal lights.
Because Acura used different lighting setups across trims, packages, and markets, it is important to check each bulb location individually before buying replacements. Use the bulb chart for the 2015 Acura MDX to confirm the correct size for each lamp and avoid ordering the wrong part.
Fitment can vary on the 2015 Acura MDX depending on trim, lighting package, body style, and whether the vehicle uses factory LED assemblies or serviceable bulbs in a given position. Some exterior lights are listed as LED, while others use traditional bulb sizes, so do not assume every lamp can be replaced with a simple plug-in bulb. If you are considering aftermarket LED conversions, make sure the bulb type, connector style, polarity, and heat management are compatible with the housing. For the best results, check the bulb currently installed in your MDX before purchasing, especially for positions that may differ by market or option package.
