    LED vs Halogen Upgrade Considerations

    When upgrading your 2014 Ram 3500 to LED bulbs, there are a few things to keep in mind. First, you may encounter CANBUS errors. This is because LED bulbs draw less power than halogen bulbs, and your truck's computer may think that a bulb is burnt out. To fix this, you will need to install a CANBUS adapter. Second, you may need to purchase adapters to fit the LED bulbs into your existing sockets. Finally, be sure to purchase high-quality LED bulbs from a reputable brand to ensure that they are bright, durable, and will not cause any damage to your truck's electrical system.
