Chevrolet Impala 2013 Bulb Size
Bulb size chart
This page helps you verify the bulb sizes for the 2013 Chevrolet Impala by lighting position, so you can match the correct replacement before you buy. Use it to check everything from headlights and fog lights to interior lamps, brake lights, and license plate bulbs.
Because bulb fitment can vary by trim, lighting package, market, and body style, the safest approach is to confirm the bulb type for the exact lamp location on your Impala. That is especially useful when replacing multiple bulbs at once or when comparing halogen and LED options.
For best results, compare the listed bulb size with the bulb already installed in your vehicle before ordering, especially if your Impala has optional equipment or a previous owner has made changes. Some positions may use standard halogen bulbs, while others may be converted to LED with aftermarket kits or replacement bulbs. Keep in mind that LED upgrades can change brightness, beam pattern, or warning behavior, so make sure the replacement is compatible with the housing and connector. If you are unsure, remove the old bulb and verify the base and marking first, then choose the closest match for your trim and lighting package.

What bulb sizes are used for the license plate and small interior lights?
The license plate light bulb, glove box light bulb, stepwell light bulb, and ash tray light bulb are all listed as 194 or 7441. These positions may share the same bulb family, but you should still verify the exact lamp location.
Does the 2013 Chevrolet Impala use LED bulbs anywhere from the factory?
The center high mount stop light bulb is listed as LED, and the fog light listing includes H11 LED and H16 LED options. Other positions on the page are listed with standard bulb types, so trim and package details matter.
Can I switch the fog lights to LED on this Impala?
Yes, the fog light listing includes H11 LED and H16 LED options. If you plan an LED conversion, check the housing depth, connector fit, and whether the beam pattern remains usable for road driving.
Why should I check the installed bulb before buying replacements?
Because trim and lighting package differences can affect fitment, and some vehicles may have been modified over time. Checking the installed bulb helps prevent ordering the wrong base, especially for exterior lamps and any aftermarket LED conversion.
