Overview of typical bulb types by location
The following list outlines the bulbs you’re most likely to encounter for a 2015 Dodge Dart, by position. Use this as a quick reference, but confirm with your vehicle’s manual or a reliable parts guide if your car has been modified or differs by market.
- Front turn signals: 7440 (amber) bulbs, 12V, single-filament. Some variations may use a dual-filament 7443 in certain markets or trims.
- Rear turn signals: 3157 (amber) bulbs, 12V, dual-filament used for both tail and turn in many configurations.
- Rear side markers/tail lamp bulbs: 194 (W5W) wedge-type bulbs, 12V, depending on exact rear lens setup.
In practice, the exact bulb can vary by trim and regional spec, so if you’re unsure, check the socket marking, remove the old bulb to match part numbers, or consult the dealer/manual to ensure you get the correct replacement.
How to identify the exact bulb for your Dart
Use these steps to verify the correct bulb type for your specific car and ensure a proper fit during replacement.
- Turn off the vehicle and open access to the relevant light housing (front bumper area for front signals, trunk/rear hatch for rear signals).
- Carefully remove the existing bulb with gloves to avoid oil contamination on the glass.
- Check the bulb base markings for part numbers (for example, “7440,” “3157,” or “194”).
- If markings are unclear, compare the bulb base and socket shape to a trusted parts guide or retailer’s compatibility tool for the 2015 Dart.
- Purchase a replacement that matches the identified bulb type and voltage (12V) and install it securely, ensuring the connector is fully seated.
If you have an aftermarket LED conversion or a nonstandard setup, bulb types can differ. When in doubt, refer to the maintenance section of your owner’s manual or contact a dealership parts department for confirmation.
