Upgrading your Ram 2500 headlights from factory halogen bulbs to bright, efficient LED bulbs is one of the most impactful and cost-effective mods you can do. This guide walks you through the entire process using high-quality Lasfit LED bulbs, perfect for Ram 2500/3500 models from 2019 to 2024 equipped with halogen headlights. Whether you’re looking for a 2019 Ram 2500 headlight bulb, a 2022 Ram 2500 LED headlight bulb size, or even a 2024 Ram 2500 LED headlight bulb upgrade, this article has you covered.
What You’ll Need
- Lasfit LED headlight bulb kit (low beam and high beam) – fits 2019–2024 Ram 2500 headlight bulb applications
- Gloves (to avoid touching bulb surfaces)
- Basic screwdriver or trim tool (optional)
- 5 minutes per side
Step 1: Preparation & Safety
- Park your truck on a flat surface and turn off the engine.
- Engage the parking brake and ensure the headlight switch is in the “OFF” position.
- Open the hood and allow the existing halogen Ram 2500 headlight bulbs to cool if the truck was recently driven.
Step 2: Accessing the Bulbs
For High Beam (9005 Bulb):
- Remove the top shroud by releasing the push clips.
- Locate the rubber dust cover behind the headlight assembly and twist it off.
For Low Beam (H11 Bulb):
- Access is easier from underneath the wheel well.
- Remove the push pin from the fender liner and pull back the liner to reveal the rubber dust cover.
📌 Owners often ask: What is the correct 2022 Ram 2500 headlight bulb size? For halogen-equipped models, the low beam is H11 (H8/9/11 compatible) and the high beam is 9005.
Step 3: Removing Old Halogen Bulbs
- Reach into the bulb socket, twist the bulb counterclockwise, and gently pull it out.
- Disconnect the wiring harness by lifting the locking tab and unplugging it.
- This process works the same if you’re doing a 2020 Ram 2500 headlight bulb replacement or even a 2021 Ram 2500 headlight bulb swap.
Step 4: Installing Lasfit LED Bulbs
- Connect the Lasfit LED bulb to the factory harness—it’s plug-and-play.
- Insert the bulb into the housing, aligning the tabs. Twist clockwise to lock it in place.
- Tuck any extra wiring neatly into the housing.
- Reattach the rubber dust cover, ensuring a tight seal.
📌 Pro Tip: The Lasfit bulbs feature built-in fans for cooling. You’ll hear a faint hum when they’re powered on—this is normal.
Step 5: Testing Before Reassembly
- Turn on the headlights and high beams to verify both bulbs work correctly.
- Check for error messages on the dashboard (Lasfit bulbs are CANbus-ready, so errors are unlikely).
- Whether it’s 2022 Ram 2500 LED headlights or a 2020 Ram 3500 headlight upgrade, always test before final assembly.
Step 6: Repeating for the Other Side
- Repeat Steps 2–5 for the opposite headlight.
- On the passenger side, removing the airbox provides extra room for easier access.
Step 7: Final Check & Night Test
- Reinstall any removed shrouds or fender liner pins.
- Once fully assembled, take your truck for a night drive to experience the dramatic improvement in visibility and the modern Ram LED headlights look.

Before You Buy: Compatibility Note
This upgrade is only for Ram 2500/3500 trucks with halogen headlights. If your truck has factory LED projectors (common on Laramie, Limited, and higher trims), the entire assembly must be replaced instead.
This applies equally to 2019 Ram 3500 headlights, 2020 Ram 2500 LED headlights, and even the 2024 Ram 2500 LED headlight bulbs.
Conclusion
Swapping your Dodge Ram LED headlights from halogen to LED is a straightforward DIY project that drastically improves nighttime visibility and gives your truck a modern, premium look. The Lasfit kit’s custom design ensures a perfect fit and optimal performance.
