What type of headlight bulb does a Chevrolet K20 Suburban use?

We created this light bulb guide to make it easier for you to find the right OEM bulbs for your car. All the data is provided for informational purposes only. The Chevrolet K20 Suburban bulb fitment guide was compiled using information from trusted lighting companies like Osram Sylvania and Philips. 

The list is a work in progress, and we reserve the right to make modifications at any time. Use this information at your own risk. We give no warranties regarding the data presented.

Why are we making such a fuss? We don't want to alarm you, but we feel obligated to inform you. This is because bulb sizes and kits can differ even within the same make, model, and year. The exact manufacturing month may occasionally have an impact on the bulb dimensions.

While we strive to be accurate, the information below may not be entirely correct for your car. Keep in mind that there is always a slight chance it could be wrong due to various factors.

Please let us know if you discover any changes that need to be made, or elements that should be included. It would be very helpful if you would do so.

Can I put LED bulbs in my Chevrolet K20 Suburban?

If you choose a Chevrolet K20 Suburban with all the bells and whistles, LED headlights may come standard. Consider the aftermarket LED bulbs as replacements for halogen bulbs on lower-level trims to gain better illumination and a longer lifespan.  

Consider legal restrictions in your State! 

A new set of LED lights for your Chevrolet K20 Suburban can improve the look and functionality of your vehicle.

If you're looking to upgrade the LED lights in your Chevrolet K20 Suburban, you'll want to take into account the legal restrictions in your area.

Because most states demand that your vehicle have yellow or white headlights, you may not be able to install headlights of different colors.

Check with your state's Department of Motor Vehicles or Department of Public Safety to determine what restrictions exist in your state before you begin shopping.

Before buying headlights or taillights, check that they have a DOT/SAE certification. This will guarantee that the light intensity is up to code for street driving.
