Partsam LED third brake light, red lens

The full-LED layout gives this Partsam replacement a clear role at the back of the cab: the red lights come on with braking, while the white outer lights serve as cargo lights linked to the interior light switch. That makes it more than a brake-light swap if your truck already has the matching cargo-light setup.

It is listed for several Super Duty, Ranger and B-Series models, but fit depends on the original equipment. Check the model years and cargo-light note before ordering.

Key points

This is a single, red-lens, chrome-housing high-mount third brake light for the rear cab roof. The listed applications include F-250, F-350, F-450 and F-550 Super Duty models from 1999 to 2016, Explorer Sport Trac from 2001 to 2005, Ranger from 1993 to 2001, and B2300, B3000 and B4000 models across the year ranges given in the product details. Part numbers listed are YC3Z13A613BA and CC3Z13A613B.

Its LED design replaces an incandescent-style lamp, and the white outer lights are intended for cargo illumination, not reversing. A practical example: when you switch on the cabin dome light to find something in the truck bed, those white lamps can illuminate the area, during braking, the red lights provide the high-mounted stop signal. Keep in mind that the listing specifies cargo-light models, a truck without factory cargo lights may require wiring or other modification.

How to use it

Installation involves cleaning the truck’s mounting area and the light’s lip with alcohol, then fitting the included rubber O-ring washers. The original screws need to be reused because replacement screws are not included. The instructions also advise against overtightening them, which matters when securing a lamp against a cab surface.

The replacement has one plug, while some factory lamps may have multiple connectors. Any extra factory sockets are meant to remain unused. The product details recommend adding clear silicone or RTV along the top as an extra precaution against water getting into the light or wiring. That is a useful step to consider, rather than assuming the supplied gasket alone will suit every installation.

Practical tips

Before starting, compare the connector and mounting arrangement with the lamp already on the truck, and confirm that the vehicle is one of the listed applications. If the truck did not originally have cargo lights, the listing says a wire from the dome light to the connector may be needed, that is a different job from a straightforward lamp replacement.

This is a more integrated approach than replacing only a failed bulb: it updates the full high-mount unit to LEDs and includes the cargo-light function described above. It may suit you if you want to replace the cab-mounted lamp and your truck has the required setup. It may not be the right fit if you need a confirmed direct replacement for a non-cargo model without making modifications.

Before you decide

Are the white lights reverse lights? No. They are cargo lights controlled by the interior light switch, the red lights operate with the brake.

Are mounting screws included? No. Keep and reuse the truck’s original screws, the rubber O-ring washers are included.

What if my truck has no cargo lights? The listing says wiring from the dome light to the connector may be needed. It also notes that non-cargo models may require modification, so this may not be a simple plug-in replacement.

In your case

Choose this replacement if your vehicle falls within the listed applications and you have the cargo-light configuration, or are prepared to handle the modification described for trucks without it. If your priority is a direct swap with no wiring changes, confirm that detail against your existing lamp first, the year range alone does not establish that every listed truck has the same connector or equipment.
