Bulb size chart
H13 Bulbs
Used for: Headlight Bulb High Beam and Low Beam
The 2014 GMC Yukon uses bulb sizes that can vary by lighting position, so it is important to confirm the correct fit before ordering replacements. This page is designed to help you verify the bulb size for each light location on the vehicle, with a focus on the headlight bulb setup used for high beam and low beam applications.
For the 2014 GMC Yukon, the available headlight bulb chart row lists H13 for the high beam and low beam function. That makes it easier to match the correct bulb to the correct lighting position and avoid buying the wrong part for your Yukon’s front lighting system.
Fitment can differ by trim level, lighting package, market, and body style, so always compare the bulb chart with the actual lamp assembly on your vehicle. Some 2014 GMC Yukon models may use halogen headlamps, while others may have different factory lighting equipment or aftermarket conversions already installed. If your Yukon has been modified with LED bulbs, HID kits, or projector-style retrofit parts, the original bulb listing may not match what is currently in the housing. Before buying replacements, check the installed bulb directly, review the owner’s manual if available, and confirm the socket style and connector shape so you can choose a bulb that fits correctly and performs as expected.
FAQ
What headlight bulb size does the 2014 GMC Yukon use?
The available bulb chart for this page lists H13 for the headlight high beam and low beam application on the 2014 GMC Yukon.
Does the 2014 GMC Yukon use the same bulb for high beam and low beam?
According to the bulb chart on this page, yes. The listed headlight bulb size is H13 for both high beam and low beam.
Why should I verify bulb size by lighting position?
Different lighting positions can use different bulb sizes, even on the same vehicle. Verifying by position helps you match the correct bulb to the correct lamp and avoid ordering the wrong replacement.
Will every 2014 GMC Yukon have the same headlight bulb fitment?
Not always. Trim level, lighting package, market, and body style can affect fitment, so it is best to confirm the bulb installed in your specific Yukon before purchasing.
Can I use an LED replacement in place of the original bulb?
Many owners choose LED replacements, but fitment and performance depend on the housing, connector, and beam pattern. An LED bulb may physically fit, but it should still be checked for proper operation and light output.
What should I check before buying a replacement bulb for my Yukon?
Check the installed bulb type, the socket style, the connector shape, and whether the vehicle has any aftermarket lighting changes. These checks help ensure the replacement matches your specific 2014 GMC Yukon.
How do aftermarket headlight conversions affect bulb fitment?
Aftermarket conversions can change the original bulb requirement. If your Yukon has been converted to HID or LED, the factory bulb listing may no longer reflect the bulb currently in the headlamp assembly.
Is the H13 bulb listing enough to order a replacement?
It is a strong starting point, but it is still smart to confirm the bulb installed on your vehicle. That is especially important if your Yukon has nonstandard lighting equipment or previous repairs.
Can I replace just one headlight bulb on the 2014 GMC Yukon?
Yes, you can replace only the failed bulb, but many drivers replace bulbs in pairs so the headlights stay similar in brightness and color over time.
What if my 2014 GMC Yukon has different lighting than the chart shows?
If the vehicle has been modified, or if it was built with a different lighting package for another market, the chart may not match your exact setup. In that case, inspect the bulb already installed in the vehicle and compare it to the chart.
Does this page help with other front lighting bulbs too?
This page is focused on the available headlight bulb row for the 2014 GMC Yukon. If you need other exterior bulb positions, check the matching bulb guide for those specific lighting locations.
What is the safest way to confirm the correct bulb before purchase?
The safest approach is to verify the bulb currently installed in your Yukon, compare it with the chart on this page, and make sure the replacement matches the socket and connector used by your vehicle.
