Freightliner bulb fitment varies by model year, factory lighting package, headlight assembly, fog-light assembly, and previous owner modifications. This guide covers common OEM-style and replacement headlight families, but factory LED headlights, HID systems, aftermarket projector headlights, sealed-beam conversions, custom marker lights, and bumper fog lights may require different bulbs or complete assemblies. Always confirm the bulb number printed on the original lamp, the assembly part number, or the VIN before ordering.
Due to manufacturer-specific variations, the information in the table may not be 100% accurate.

FAQs
Check the model, year, lighting position, original bulb number, connector style, and headlight or fog light assembly. Also confirm whether the truck has factory lighting, aftermarket lights, LED conversions, or custom bumper lights.
This is the best way to avoid ordering the wrong Freightliner headlight bulb, fog light bulb, signal bulb, or marker light.
Some Freightliner LED headlights do not use standard replacement bulbs. Factory LED and aftermarket LED headlight assemblies may use integrated LEDs, replaceable modules, or complete assembly replacement.
If your Freightliner has LED headlights, do not order halogen bulbs unless the assembly specifically uses a replaceable halogen bulb for that position.
Your Freightliner bulb size depends on the model, year, headlight assembly, and lighting package. Freightliner trucks may use halogen bulbs, sealed-beam headlights, HID lights, LED modules, or aftermarket headlight assemblies.
Always confirm the bulb number printed on the original bulb or check the headlight, fog light, or signal light assembly before ordering. Freightliner Cascadia, Century, Classic, Columbia, Coronado, and M2 trucks do not all use the same bulbs.
