LED Side Marker Light Bulbs Buying Guide
What Is a Side Marker Light Bulb?
A side marker bulb lights the front or rear marker on the side of a vehicle. Side marker lights help other road users see the vehicle’s position and overall length from the side.
Some markers are separate lamps, while others are built into a headlight or tail light housing. This collection contains replacement bulbs, not complete side marker light assemblies.
Front and Rear Side Marker Light Bulbs
Front and rear marker bulbs serve the same basic purpose but use different output colors.
Position |
Common Location |
Required Output |
|---|---|---|
Front side marker light |
Near the headlight, front fender or bumper corner |
Amber |
Rear side marker light |
Near the tail light or rear quarter panel |
Red |
The bulb and lens work together to produce the final color. Confirm the required output before choosing a white, amber or red bulb.
Common LED Side Marker Light Bulb Sizes and Types
T10/194 LED bulbs are commonly used in automotive side marker lights. Related product listings may include the following bulb numbers:

Fitment Note |

General wedge-base bulb family |
194 |

A product may list T10, 194, 168, 2825 and W5W together, but this does not guarantee vehicle fitment. Check the number on the original bulb. A vehicle with a sealed, integrated LED marker may require a complete lamp assembly instead of a replacement bulb.
How to Choose an LED Side Marker Bulb
- Check the position: Confirm whether the failed bulb is in the front or rear marker.
- Match the bulb size: Use the number on the original bulb or in the vehicle manual.
- Confirm the output color: Front markers normally need amber light, while rear markers normally need red light.
- Compare the dimensions: Make sure the LED bulb fits inside the factory housing.
- Check electrical compatibility: Some vehicles may show flickering or a dashboard warning after an LED upgrade.
- Inspect the lamp: A new bulb cannot repair a damaged socket, cracked lens or wiring fault.
Vehicle year, make, model, trim and marker position can change the required bulb. Use the Automotive Bulb Finder to check the correct size before ordering.

FAQs
It is the marker lamp built into or placed beside the headlight housing. It normally shows amber light to the side and is separate from the high- and low-beam functions.
Switch off the lights, open the housing or access panel and remove the old bulb. Install a matching replacement and test it before closing the housing. Access steps vary by vehicle.
The cost depends on the bulb and installation access. Replacing only the bulb usually costs less than replacing the complete side marker lamp. Labor may cost more if panels or the light assembly must be removed.
A required side marker light must remain in working condition. A failed marker may lead to an inspection failure or citation, depending on local laws. Replace it promptly and check your state’s requirements.
