2019 Ram 3500 Bulb Size Guide

Quick Reference Bulb Size Chart: 2019 Ram 3500

Note on Trim Level Variations: The 2019 Ram 3500 was available with several different trim levels, and some of the higher-end trims (such as the Laramie, Longhorn, and Limited) came with factory-installed HID or LED headlights. If your truck has these, the bulb sizes will be different. For example, some models use a D3S bulb for the HID low beams and a 9005 for the high beams. Always check your owner's manual or existing bulbs before ordering replacements.

LED vs. Halogen Upgrade Considerations

Upgrading your 2019 Ram 3500's halogen bulbs to LEDs can provide a significant improvement in visibility and give your truck a more modern look. However, there are a few things to keep in mind before you make the switch:

• CANBUS Errors: The 2019 Ram 3500 uses a CANBUS system to monitor the vehicle's electrical components, including the lights. When you install an LED bulb, the lower power draw can sometimes trick the CANBUS system into thinking that the bulb is burnt out. This can result in a "bulb out" warning on your dashboard and, in some cases, the LED bulb may not function correctly. To avoid this, you'll need to install a CANBUS-compatible LED bulb or use a separate resistor kit.
• Adapters: Some LED headlight bulbs may require a special adapter to fit properly in the 2019 Ram 3500's headlight housing. These adapters are usually inexpensive and easy to install, but it's important to make sure you get the right ones for your specific bulbs and vehicle.
• Beam Pattern: When upgrading to LED headlights, it's important to choose a bulb that is designed to mimic the beam pattern of the original halogen bulb. This will ensure that you get the best possible visibility without blinding other drivers.

How to Replace Each Bulb

Here are some quick tips for replacing the most common bulbs on your 2019 Ram 3500:

• Headlights: The headlights are located in the front of the truck, on either side of the grille. To access the bulbs, you'll need to open the hood and remove the plastic cover behind the headlight housing. Once the cover is removed, you can twist the bulb socket to remove it and then pull the old bulb out. When installing the new bulb, be careful not to touch the glass with your bare hands, as the oils from your skin can cause the bulb to overheat and fail prematurely.
• Fog Lights: The fog lights are located in the lower front bumper. To access the bulbs, you'll need to crawl under the front of the truck and remove the plastic splash shield. Once the shield is removed, you can access the back of the fog light housing and replace the bulb.
• Tail Lights: The tail lights are located in the rear of the truck, on either side of the tailgate. To access the bulbs, you'll need to open the tailgate and remove the two screws that hold the tail light housing in place. Once the screws are removed, you can pull the housing straight back to access the bulbs.
• License Plate Lights: The license plate lights are located above the license plate. To access the bulbs, you'll need to remove the plastic cover that surrounds the lights. Once the cover is removed, you can twist the bulb sockets to remove them and then pull the old bulbs out.
• Dome/Map Lights: The dome and map lights are located in the overhead console. To access the bulbs, you'll need to pry the lens cover off with a small flathead screwdriver. Once the cover is removed, you can access the bulbs and replace them.

Common Lighting Issues for This Generation

The 2019 Ram 3500 is a reliable truck, but there are a few common lighting issues that you may encounter:

• Prematurely Burnt-Out Bulbs: Some owners have reported that the headlights and other bulbs on their trucks have a tendency to burn out prematurely. This can be caused by a number of factors, including a faulty voltage regulator or a loose connection.
• Condensation in the Headlight Housings: It's not uncommon to see a small amount of condensation inside the headlight housings, especially after a car wash or a heavy rain. However, if you notice a large amount of water inside the housings, it could be a sign of a bad seal.
• Flickering Lights: Flickering lights can be caused by a number of issues, including a loose connection, a faulty ground, or a problem with the CANBUS system. If you're experiencing this issue, it's a good idea to have a qualified mechanic diagnose the problem.
