Cracked signal lens, fog behind the plastic, or a tow mirror signal that still blinks like it is 2015? The smoked LED sequential tow mirror signal pair replaces the whole signal lamp on 2015-2022 Ford F-150 tow mirrors. Each lamp carries 96 LEDs behind a smoked lens and plugs into the factory connector.

A tow mirror is the tall extended mirror you use for towing trailers. Its signal lamp sits in the outer shell and takes every parking-lot hit. That is why it fails before anything else on the mirror.

What sequential actually buys you

A stock signal blinks on and off as one block. A sequential signal lights its LED segments in a sweep, from the inner edge out to the tip. Same warning, but easier for the driver behind you to read.

This pair does three jobs in one sealed housing. It runs an amber DRL, short for daytime running light, the lamp that stays on while you drive. It adds a white towing parking light, then sweeps amber when you signal.

• Amber DRL while driving.
• White towing parking light for night hookups.
• Amber sequential sweep every time you signal.

The housing is rated IP67 — sealed against dust and able to survive a dunk in water, not just a rain shower. KOEEP lists a 1-year warranty on the pair.

Lens, glass, or whole mirror? Order the right part

Most buyers only need the signal lamp. Use this check before you order anything:

• Lens cracked, LEDs dead, or you want the sequential look → the signal pair in this guide.
• Glass cracked or the defroster dead → the heated upper mirror glass (FL3Z17K707T / FL3Z17K707R) for 2015-2022 F-150 and Super Duty.
• Shell broken, motor dead, mirror hanging loose → a full mirror, like the power heated passenger side tow mirror for 2015-2020 Ford F-150.
• Both mirrors tired at once → the power tow mirror pair with temperature sensor for 2015-2020 Ford F-150.

A mirror signal is only one lamp on the truck. Everything else you might need, from bulbs to full light assemblies, sits in the lighting and lamps collection.

How to swap it: about 30 minutes

You do not need to pull the mirror off the door. This is the forum-documented order of work for 2015 and newer tow mirrors:

1. Fold the mirror in and pull out the upper and lower glass.
2. Unplug the heated glass and signal connectors.
3. Remove the five 7 mm screws hidden behind the glass.
4. Split the housing halves by releasing the snap clips.
5. Unclip the old signal lamp and plug the new lamp in.
6. Test both functions before you snap the housing shut.

Take photos at every step. Clip orientation is easy to forget and hard to fix with the housing half closed.

Hyper flash: the one problem you can plan for

Hyper flash is the signal blinking at roughly twice normal speed. It is the truck saying a bulb is missing, because LEDs draw far less current than the old bulb.

This pair is sold as plug and play. Some F-150s still read the low draw as a dead bulb and fast-blink anyway. If yours does, this is the standard fix:

• Add one 6-ohm 50-watt load resistor in parallel across each new lamp, bridging its power and ground wires.
• Mount each resistor on bare metal, away from plastic, paint and wiring looms.
• Expect real heat — owners report these resistors running hot within seconds.
• Do both sides, even if only one side fast-blinks.

A load resistor makes the circuit draw about as much current as the old bulb, so the truck stops complaining. Newer F-150s watch bulbs through the body control module, so a resistor beats a flasher relay swap.

Is a smoked lens legal on the road?

Short answer: yes, as long as it lights amber. Federal rule FMVSS 108 sets turn signal color, output and placement. SAE J588 is the test standard behind it.

The smoked shell is only the unlit look. Lit up, this pair projects amber, which is what the rule checks. KOEEP lists the pair as DOT-certified and SAE-certified.

Driving a GM truck instead?

The same sealed sequential upgrade exists for GM trucks. The sequential LED mirror signal for 2020-2023 Silverado and Sierra fits 2020-2024 2500HD and 3500HD and cross-references GM numbers 84468924 through 84468927.
