2016 Ford F-250 Super Duty Bulb Size Guide

Quick Reference Bulb Size Chart: 2016 Ford F-250 Super Duty

Note: The 2011-2016 Super Duty generation did not offer factory HID, LED, or projector headlights. All trims from XL to Platinum used the same H13 dual-filament halogen bulb in a reflector housing.

LED vs. Halogen Upgrade Considerations

Upgrading the stock halogen bulbs in your 2016 F-250 to modern LEDs can dramatically improve night-time visibility and give your truck a more modern appearance. However, there are a few key things to consider before you make the switch.

• CANBUS Errors: Ford trucks of this era are generally not prone to "bulb out" warnings or hyperflashing (for turn signals) when switching to LEDs. Their electrical systems are less sensitive than many European vehicles. However, it's always a good practice to buy "CANBUS-ready" or "error-free" bulbs, as they have built-in resistors to mimic the power draw of a halogen bulb, ensuring compatibility.
• Adapters and Fitment: For the H13 headlights, most LED replacement bulbs are designed to be plug-and-play, fitting directly into the stock housing and connector. The main challenge is often ensuring the bulb's heat sink or fan has enough clearance behind the headlight assembly. For other bulbs like the 3157 or 194, LED replacements are a direct swap.
• Beam Pattern: This is the most critical factor for headlight upgrades. The stock F-250 headlight housing is a reflector designed for a halogen bulb's 360-degree light output. Dropping in an LED bulb can create an improper and dangerous beam pattern, causing glare for oncoming drivers. Look for high-quality LED bulbs with adjustable collars that allow you to rotate the bulb. The goal is to position the LED chips to fire horizontally (left and right) to best replicate the original beam pattern.

How to Replace Each Bulb

Replacing bulbs on the 2016 Super Duty is a straightforward task that most owners can do at home with basic tools.

• Headlights (H13): Access is surprisingly easy. Open the hood and locate the top of the headlight assembly. You'll see two metal retaining clips holding the assembly in place. Pull them straight up. The entire headlight housing can now be pulled forward and out of the truck. From the back, twist the large dust cover off, then twist the bulb retaining ring to remove and replace the H13 bulb.
• Fog Lights (9140): These are best accessed from underneath the front bumper. You may need to remove a small plastic splash shield. Reach up, twist the bulb socket out of the fog light housing, replace the bulb, and re-insert.
• Front Turn Signals (3157A): These are located in the main headlight assembly. Follow the same procedure as removing the headlight. The turn signal socket is a simple twist-lock on the side of the housing.
• Tail Lights / Brake / Reverse (3156/3157): Lower the tailgate. You'll see two bolts (typically 8mm or 10mm) on the inside edge of the truck bed holding the tail light assembly. Remove these two bolts. Carefully pull the tail light housing straight back to release it from the plastic retaining clips. The bulb sockets twist out from the back of the housing.
• License Plate & Cargo Lights: These are the easiest. The license plate light lenses often have a small tab to release them, or they can be gently pried out with a flathead screwdriver. The cargo light bulbs are accessed by removing the two screws holding the lens assembly to the back of the cab.
• Interior Dome/Map Lights: Use a plastic trim removal tool or a small flathead screwdriver (wrapped in tape to prevent scratching) to gently pry the clear lens cover off. The bulbs can then be pulled straight out.

Common Lighting Issues for this Generation F-250

The 2011-2016 Super Duty trucks are known for their reliability, but a few common lighting issues can pop up.

• Melted DRLs: Because the Daytime Running Lights use the H13 low beam filament at reduced power, it generates constant heat. Over many years, this can cause the amber plastic DRL reflector inside the headlight housing to become brittle and discolored, and in some cases, even melt the housing itself. Check for signs of browning or charring when you replace your bulbs.
• Socket Corrosion: The rear tail light sockets, especially the one for the brake/turn signal, can sometimes accumulate moisture, leading to corrosion on the electrical contacts. This can cause intermittent bulb function or rapid bulb burnout. A small amount of dielectric grease applied to the bulb contacts during replacement can help prevent this.
• Wiring Harness Issues: While less common, the wiring harnesses, particularly for the headlights and tail lights, can become brittle over time. If a bulb is good but still won't light up, inspect the connector and wiring for any cracks, breaks, or corrosion.
