If you’re looking for the Ford F-250 F-350 bulb size guide, this post covers everything you need from 2020, 2021, to 2022 Ford F-250 F-350 models. Whether you need to replace your factory halogen bulbs or upgrade to brighter LEDs, we’ve listed the exact bulb sizes to help you quickly find the right fit for your headlights, fog lights, turn signals, brake lights, and more.

This guide applies to multiple Ford F-250 F-350 trims, including XL, XLT, STX, Lariat and King Ranch.

Since aftermarket LED bulbs can only replace OEM halogen bulbs, we do not list compatible LED options for the 2020–2022 Ford F-250 F-350 models that already come equipped with factory LED headlights.

When searching through Lasfit’s “Select Your Vehicle” tool, you’ll notice that for 2020–2022 Ford F-250 F-350, bulb sizes differ depending on the trim level. You can select your specific trim to find the compatible headlight bulbs, fog lights, turn signal lights, and more for your Ford F-250 F-350.

For your convenience, we’ve organized all the information into five lighting categories, each with easy-to-read bulb size charts. Click any category below to jump straight to the chart you need.

• Although the H13 is a dual-beam bulb, for the 2020–2022 Ford F-250 and F-350, if you’re replacing both the low and high beam headlight bulbs, you will need two pairs (four pieces) of H13 LED bulbs.
• Lasfit LS Plus H13 LED headlight bulbs are available for the 2020–2022 Ford F-250 and F-350, delivering 65W power, 6500LM ultra brightness, excellent heat dissipation,and a plug-and-play installation experience.

• Lasfit LED fog light bulb replacements are available only for Ford F-250 F-350 models that come with factory halogen fog lights.
• For Ford F-250 F-350 owners, off-road performance is everything — and lighting design plays a key role. Lasfit offers the LD Plus H10 Switchback Fog Lights, a dual-color LED bulb that delivers 3000K amber yellow for foggy or dusty trails and 6000K bright white for clear night driving. These switchback fog lights not only improve visibility but also give your Grand Cherokee a stylish and rugged off-road look.

• For the Ford F-250 F-350 front turn signal lights, they share the same bulb with the front parking lights. The bulb size is 4257, so you only need one pair (2 PCS) of 4257 bulbs to replace the front turn signal lights and front parking lights together.
• For Ford F-250 F-350 models with halogen turn signal lights, Lasfit offers our most powerful T3 Series turn signals. These bulbs feature a built-in CANBUS decoder and a more compact size for easier installation.
• For the 2020–2022 Ford F-250 and F-350 front turn signals, you can choose switchback LED bulbs, which means you’ll get amber front turn signal lights and white front parking lights. Alternatively, you can go with full amber LED bulbs, so both your front turn signal lights and front parking lights will be amber.
