Note. Classic sealed-beam models need separate handling from newer pod, HID, LED, or rectangular assemblies.
Accuracy and completeness are very important to us and our followers. If you notice any incorrect or missing information, please let us know so we can update the guide promptly. Your feedback is greatly appreciated.
Depending on the year of the model, some fitments may differ from the ones listed, please verify your sockets before purchasing.
Volvo VN: identify the model and headlamp
VN is too broad for one bulb chart. Use the truck’s exact model and the headlamp fitted to it. For a VNL, the section below separates older bulb-style headlights from factory LED and identified replacement housings.
Volvo VNL bulb sizes by headlamp type
For an older VNL housing fitted with an H11 projector low beam and a separate 9005 reflector high beam, use the chart below. The bulb-style arrangement is separate from factory LED and aftermarket headlamps; a model year or projector lens alone does not identify it.
| Light position | Size for this bulb-style headlamp |
|---|---|
| Projector low beam | H11 |
| Reflector high beam | 9005 (HB3) |
| Front turn / parking lamp with a replaceable 3157 bulb | 3157 |
Open the full Volvo VNL bulb and headlamp guide for the factory LED branches, exact replacement-assembly chart and more bulb choices.
Browse Alpha Series H11 low-beam and 9005 high-beam options for the matching bulb sockets, plus 3157 amber signal bulbs for a housing using that replaceable bulb. Match the installed housing and the selected bulb’s installation instructions.
LED headlight conversion bulbs may not comply with FMVSS/CMVSS requirements for on-road use. Check applicable state and provincial laws before use.
Signal bulb selection: Do not use the Alpha bulb where the high-power signal circuit stays on continuously as a daytime running light. Choose by the actual circuit operation; a continuously lit lamp does not by itself establish that the circuit uses PWM.
Factory LED: Volvo’s older optional Truck-Lite LED headlights and the redesigned LED VNL are separate headlamp configurations. The redesigned VNL brochure specifies LED headlights, turn signals, marker and parking lamps; it does not identify a 3157 replacement bulb for that arrangement.
Replacement housings: United Pacific 31445–31448 specify H7 low, H1 high, 1157 turn and 194 side marker. The 31094–31097 family has LED headlights with a 3157 turn bulb. Its 35753–35756 all-LED family is specifically for factory-LED-equipped 2013–2017 VN/VNL trucks. These assembly specifications do not rewrite the original-bulb chart.
Sources: Volvo VNL brochure, printed pages 50–51; United Pacific catalog, printed pages 33–34.
The Alpha Series PWM module is an optional accessory for suitable flicker or bulb-out applications. It is rated for 9–16V DC; select the connector matching the installed bulb and use it only when the lighting circuit and product instructions call for a module. Complete LED assembly conversions can have separate LCM requirements.
Due to manufacturer-specific variations, the information in the table may not be 100% accurate.

FAQs
The older bulb-style arrangement covered here uses H11 low beam and 9005 high beam. Factory LED headlights and replacement housings need their own specifications: for example, the identified United Pacific 31445–31448 projectors use H7 low and H1 high.
Use the exact truck model and installed lamp type. The VN name alone does not establish one low-beam, high-beam or signal-bulb size.
It can. United Pacific 31094–31097 assemblies have LED low and high beams with an included 3157 turn bulb. Other LED headlamps use LED turn lamps. Identify the housing before applying a signal-bulb size.
