This 2019 RAM 2500 bulb size guide helps you verify the correct bulbs by lighting position, so you can match the right part before you buy. Because trim, body style, and lighting package can change the fitment, it is important to check the exact lamp location on your truck instead of relying on a single bulb number for every version.
Use this page to compare the headlight, tail light, brake light, reverse light, marker light, and interior bulb sizes for the 2019 RAM 2500. Whether your truck uses projector-type headlights or the non-projector setup, the bulb chart below is organized to make replacement faster and reduce the chance of ordering the wrong bulb.
Fitment can vary by market, cab style, bed length, and factory lighting package, so always confirm the bulb type for your specific truck. Some positions use halogen bulbs, while others may use LED assemblies or LED-style service parts depending on trim. If you are considering an aftermarket LED conversion, make sure the bulb base, polarity, beam pattern, and any required resistors or adapters are compatible with your RAM 2500. The safest approach is to inspect the installed bulb before purchasing, especially for exterior lamps that may differ between projector and non-projector headlights.
The 2019 RAM 2500 can use different headlight bulbs depending on the headlight design. High beam is listed as 9005. Low beam is 9005 for projector-type headlights and H11 for non-projector headlights.
Check the front lamp housing. Projector headlights have a distinct round lens element inside the headlamp assembly, while non-projector headlights use a different reflector-style layout. The bulb size depends on that design.
Front turn signal bulb size depends on the headlight setup. With projector-type headlights, the front turn signal is LED. Without projector-type headlights, it uses 3157A.
For projector-type headlights, the brake light bulb is LED. For non-projector setups, the brake light bulb is 3057R.
Rear turn signal bulb size also depends on the lighting package. With projector-type headlights, it is LED. Without projector-type headlights, it uses 3057.
Tail light bulb size is LED on trucks with projector-type headlights. On trucks without projector-type headlights, the tail light bulb is 3157R.
Reverse light bulb size depends on the headlight package. With projector-type headlights, it uses 7440. Without projector-type headlights, it uses 921.
The license plate light bulb is listed as 194 or 7441 for the 2019 RAM 2500.
Common interior bulb sizes include 578 for the map light, 194 or 7441 for the glove box light, and 921 for the trunk or cargo area light.
No. The center high mount stop light bulb is 921, while the reverse light uses either 7440 or 921 depending on whether the truck has projector-type headlights.
Not always. With projector-type headlights, both front and rear side marker bulbs are LED. Without projector-type headlights, the front side marker is 3157A and the rear side marker is 3057A.
Check the exact lamp position, whether your truck has projector-type headlights, and the bulb currently installed. Trim and lighting package differences can change fitment, so matching the installed bulb is the best way to avoid ordering the wrong part.
