2022 International MV Bulb Size Guide

Quick Reference Bulb Size Chart: 2022 International MV

Note: The 2022 International MV series predominantly uses halogen and incandescent bulbs from the factory. Higher trim levels or optional packages may feature factory-installed LED units, which are sealed and not designed for simple bulb replacement. If your truck has these, the entire housing typically needs to be replaced if it fails. Always double-check your existing bulbs before purchasing replacements.

LED vs. Halogen Upgrade Considerations

Upgrading your 2022 International MV's lighting to LED can significantly improve visibility and give your truck a more modern look. However, there are a few key things to consider before you make the switch.

• CANBUS Errors: Modern trucks like the MV use a CANBUS system to monitor the vehicle's electrical components, including the lights. LED bulbs draw significantly less power than their halogen counterparts. This lower power draw can sometimes trick the CANBUS system into thinking a bulb is burned out, resulting in a "bulb out" warning light on your dashboard. To prevent this, you may need to install CANBUS-compatible (or "error-free") LED bulbs, which have built-in resistors to mimic the power draw of a halogen bulb.
• Load Resistors & Adapters: For turn signals, the lower resistance of LED bulbs can cause "hyperflashing," where the signal blinks much faster than normal. To correct this, you will need to wire a load resistor across the positive and negative wires for each turn signal bulb. Additionally, while most LED replacement bulbs are designed to be plug-and-play, some headlight or fog light kits may require a specific adapter to fit securely into the factory housing. Always check the product description to see if adapters are included or needed.
• Beam Pattern: When upgrading headlights, it is crucial to choose high-quality LED bulbs that are designed to replicate the filament position of the original halogen bulb. This ensures that the light is focused correctly by the headlight housing, providing a clean and effective beam pattern that illuminates the road without glaring and blinding oncoming drivers.

How to Replace Each Bulb

Replacing the bulbs on your 2022 MV is generally straightforward. Here are some quick tips for each location.

• Headlights & Fog Lights (H11, 9005): Access is typically gained from behind the headlight assembly inside the engine bay. You may need to move the windshield washer fluid reservoir or other components for better access. The bulbs twist out of the housing counter-clockwise. Wear gloves to avoid touching the new bulb's glass with your bare hands, as oils from your skin can cause premature failure.
• Turn Signals, Brake, and Tail Lights: The rear combination lamps are usually held in by a few screws accessible from the outside or inside of the lamp assembly. Once the housing is removed, the bulb sockets twist out from the back. The front turn signal is located within the main headlight assembly and is accessed similarly to the headlights.
• Reverse & License Plate Lights: Reverse lights are part of the main tail light assembly. The license plate light housing is typically a small, separate unit held in by clips or small screws. The cover pops off to reveal the 194 bulb.
• Side Markers: These are often removed by pushing the entire housing to one side and prying it out. The bulb socket then twists out from the back of the housing.
• Dome/Map Lights: Use a plastic trim removal tool or a small flathead screwdriver to carefully pry off the clear lens cover. The 194 bulb can then be pulled directly out of its socket.

Common Lighting Issues for this Generation

While the 2022 MV is a robust truck, a few common lighting issues can arise, often related to the heavy-duty nature of its use.

• Vibration-Related Failures: The constant vibration of a commercial truck can shorten the lifespan of standard incandescent and halogen bulb filaments. If you find yourself replacing bulbs frequently, upgrading to high-quality, vibration-resistant LED bulbs is an excellent long-term solution.
• Wiring and Connector Corrosion: Exposure to road salt, moisture, and dirt can lead to corrosion on bulb sockets and wiring connectors. This can cause intermittent flickering or complete failure of a light. Regularly inspecting and cleaning these connections with a wire brush and applying dielectric grease can prevent these issues.
• Voltage Irregularities: Issues with the vehicle's alternator or voltage regulator can cause bulbs to burn out prematurely. If you've ruled out vibration and connection problems, it may be worth having a technician test your truck's electrical system.
