For a 2010 Ford Edge, the rear tail/stop lights are usually powered by a dual‑filament bulb in the 3157 family, with the turn signal often using a separate single‑filament bulb such as the 3156. Exact part numbers can vary by market and trim, so verify the specific bulb on your vehicle or consult the owner’s manual.
Identify the correct bulb for your Edge
To ensure you buy the right bulbs, start by confirming the exact bulb type on your specific car. The safest approach is to read the markings on the bulb itself, or consult Ford’s parts diagrams for your VIN. Below are the two most common configurations you’ll encounter in the 2010 Edge rear lamp assemblies.
- Tail/Brake lamp bulb: Dual‑filament 3157 family (commonly 3157 or its variants such as 3157NA/3157K depending on region). This bulb handles both the tail light and the stop/brake function in the same bulb.
- Turn signal lamp bulb: Single‑filament bulb, typically around 3156 in many 2010 Edge rear housings. Some configurations may use a 3157 variant for the turn signal as well, so confirm by matching the socket and bulb shape.
Conclusion: Because Ford used a few regional or trim‑level variations, the exact bulb code can differ. Always verify by inspecting the current bulb or checking an official parts diagram for your vehicle’s VIN.
How to verify and replace the bulbs
The following steps guide you through verifying the correct bulbs and performing a safe replacement.
- Open the tailgate and access the rear lamp housing. Remove any screws or clips to detach the assembly as needed.
- Carefully remove the bulb socket from the housing by turning it counterclockwise and pulling straight out.
- Check the bulb base markings or compare the bulb’s shape to a 3157 dual‑filament and a 3156 single‑filament; if in doubt, reference the owner’s manual or a Ford parts diagram for your VIN.
- Purchase the correct bulb: 3157 for tail/stop, and 3156 for turn signals (if your vehicle uses separate bulbs). If your vehicle uses a different variant in your market, adjust accordingly.
- Install the new bulb by seating it in the socket, reinsert the socket into the housing, reattach the lamp assembly, and test the lights before finishing.
Tip: If you’re considering LED replacements for brighter output, ensure they’re CANBUS‑compatible and account for any necessary load resistors to prevent hyper‑flash or bulb‑out warnings.
Notes for shoppers and technicians
Always cross‑check with Ford’s official parts diagrams or a trusted parts retailer using your vehicle’s VIN. Bulb availability and part numbers can differ by country, dealership, and production run.
Summary: For a 2010 Ford Edge, expect a 3157 dual‑filament bulb for the tail/stop lights and a 3156 (or occasionally a 3157 variant) for the turn signals. Confirm on the actual bulb or via a parts diagram for your exact vehicle, then follow standard replacement steps to install the correct bulbs safely.
