This 2020 Chevrolet Bolt EV bulb size guide helps you verify the correct bulbs by lighting position before you buy replacements. Use it to match the bulb type for the headlights, tail lights, turn signals, interior lamps, and cargo-area lights on your Bolt EV.
Because lighting equipment can vary by market and body style, the best way to use this page is to compare each location on the vehicle with the bulb chart. That makes it easier to confirm the right fit for the front, rear, and cabin lighting on your 2020 Bolt EV.
For fitment, always check your trim and lighting package first, since some 2020 Bolt EV models may differ by market or equipment level. A few positions use LED assemblies, while others use replaceable bulbs, so do not assume every lamp can be swapped the same way. If you are considering an aftermarket LED conversion, make sure the bulb base, polarity, and beam pattern are compatible with the housing. It is also a good idea to inspect the installed bulb before ordering, especially for positions like the D3S headlight bulb, 7444NA front turn signal and parking bulbs, 921 interior and cargo bulbs, 194 glove box and courtesy bulbs, 2825 cabin and exterior accent bulbs, and 7440 rear brake and turn signal bulbs.

Not always. Trim, lighting package, market, and body style can change the exact setup, so it is best to confirm the bulb position on your specific vehicle.
Some LED-equipped positions are not simple bulb swaps. If you plan an aftermarket conversion, check the housing, connector, polarity, and compatibility before buying.
