Fits: 2015-2020 Ford F-150 — all trims without the factory BLIS blind spot monitoring system.
Confirm your truck does not have OE BLIS before ordering. This is the one check that decides whether the set fits at all.
About the Red and Amber Together
The 2015-2020 F-150 was sold in two US-spec turn signal configurations. One of them uses a shared brake and turn signal circuit: on the factory lamp both sides simply light solid red at the same time.
These lights keep that same simultaneous behaviour but show it in red and amber dual colour. Seeing red and amber light together is the normal US-spec working state on that configuration, not a product defect. If yours does this, nothing is wrong.
Before You Start
- Park on level ground, switch off, and disconnect the negative battery terminal while handling wiring.
- Use masking tape along the painted bedside and around the tailgate opening.
- Do not put dielectric or weather-sealing grease on connectors or sockets.
- If a lamp does not move, stop and look for another fastener rather than forcing it.
Required Tools
- 8 mm socket and ratchet
- Small flat-head screwdriver or pry tool, for the tailgate damper clip
- Trim removal tool
- Masking tape and clean microfiber towels
- A helper for brake light and reverse light testing
Part 1: Remove the Factory Tail Lights
Step 1: Remove the Tailgate Assist Damper, If Fitted
Open the tailgate. If your truck has a tailgate assist damper, use a small flat-head screwdriver or pry tool to release the metal retaining clip, then pull the damper end off its mounting stud.
Step 2: Remove the Two Mounting Bolts
Use an 8 mm socket to remove the two bolts on the inner side of the factory lamp.
Step 3: Pull the Lamp Out and Unplug It
Pull the assembly straight rearward to release it from the locating pins, then press the connector locking tabs and disconnect.
Part 2: Install the New Tail Lights
Step 4: Connect and Fit
On applicable US-spec trucks without the factory radar system, connect the supplied adapter harness. Connect the green connector to the lower reverse-light connection — that one is easy to leave off, and reverse is the function you lose if you do.
Align the locating pins with the body openings, press the assembly firmly into position, and refit the two 8 mm bolts.
Step 5: Refit the Damper and Test
If you removed the tailgate assist damper, press it back onto its mounting stud and confirm it is securely attached. Then switch the lights on and test:
- Running and parking lights on both sides.
- Brake lights, with a helper on the pedal.
- Left and right turn signals, hazards and the sequential sweep.
- Reverse lights, with the truck safely in reverse and the parking brake on.
- Startup animation, once the road-light functions pass.
- Check for dashboard warnings, hyperflash or flicker.
Common Issues and Solutions
Reverse light does not work. The green connector was not connected to the lower reverse-light connection. Check it at both ends.
Red and amber light at the same time. Normal on the US-spec shared brake and turn signal configuration. Not a fault.
One lamp does not turn on. Recheck the main connector lock, the related fuse and the battery connection.
Swap test. If a lamp still does not work, swap the left and right units to find out whether the issue is the light or the truck's wiring.
Warning, flicker or hyperflash. Confirm the adapter harness and any included decoder or resistor is connected and secured.
The lamp will not sit flush. Check for a trapped harness, or a locating pin that has not seated.
Condensation inside the tail light. Temperature differences can cause light condensation, which is normal. Once the light has been on for a while and the internal temperature stabilizes, the moisture clears on its own. It does not affect brightness, performance, or lifespan.
