Chevrolet Corvette 2021 Bulb Size
Bulb size chart
This page covers the 2021 Chevrolet Corvette and helps you verify bulb sizes by lighting position, so you can match the correct replacement to the exact lamp on the car. Because the Corvette uses different bulbs for different exterior and interior locations, checking the position first is the safest way to avoid ordering the wrong part.
For this model year, many exterior lighting functions use LED assemblies, while a few service points still rely on replaceable bulbs. The chart is organized to make it easy to identify the headlight, tail, brake, turn signal, reverse, marker, license plate, and cabin light locations before you buy replacements.
Fitment can vary by trim, lighting package, market, and body style, so always compare the bulb position on your vehicle with the chart before purchasing. Some 2021 Corvette lighting is factory LED and may not use a traditional replaceable bulb, while other locations such as the trunk or cargo area light and license plate light may use serviceable bulb types. If you are considering an aftermarket LED conversion, check polarity, socket style, and any warning or compatibility issues before installation. It is also a good idea to inspect the installed bulb or assembly first, especially if your car has been modified or if you are unsure whether a previous owner changed the lighting setup.

What bulb is used for the rear turn signal on this model year?
The rear turn signal light bulb position is listed as LED. Check the specific rear lamp assembly on your Corvette, because LED-equipped lighting can differ from one trim or market to another.
