If you want a high-mount stop light specifically engineered for the 1999-2007 Chevy Silverado and GMC Sierra, choose PIT66 LED 3rd; if you need a complete pair of replacement taillight assemblies for the 2009-2014 Ford F-150, choose OKLPF Rear Brake Tail. These two products serve entirely different vehicle generations and mounting positions, so the decision isn't about which is "better" in a vacuum, but which one actually fits your truck's rear end.
• PIT66 LED 3rd: Offers superior weather sealing with high-density foam padding for a watertight seal on older GM trucks, though it is strictly a single-unit third brake light rather than a full tail light assembly.
• OKLPF Rear Brake Tail: Delivers a full dual-side replacement solution with rigorous environmental testing against salt spray and humidity, but it explicitly excludes fitment for Flareside or Stepside bed styles.
• Who picks PIT66: Owners of 1999-2007 Silverado/Sierra models who need to upgrade their cargo area visibility without replacing their entire rear lighting cluster.
• Who picks OKLPF: Drivers of 2009-2014 F-150s (Standard Bed) looking to refresh both driver and passenger side lights simultaneously with direct plug-and-play simplicity.
The PIT66 LED 3rd is designed for a very specific niche: restoring or upgrading the high-mounted stop light on first-generation GMT800 platform trucks. If you drive a 1999 through 2007 Chevrolet Silverado or GMC Sierra in any configuration—whether that is the 1500, 2500, 3500, or their Heavy Duty counterparts—this unit is built to slot right into the factory opening. The product data sheet highlights compatibility with reference part numbers 5978318 and 16525205, ensuring that this isn't a generic aftermarket guess but a targeted replacement for those exact OEM specifications.
What stands out most about this design is its approach to durability in harsh conditions. The manufacturer has padded the back of the cover with high-density foam and ensured the unit is perfectly sealed around the edges. This isn't just about aesthetics; it is a functional waterproof design intended to prevent water, mud, and snow from leaking inside the housing. For SUV owners and truck drivers who navigate snowy winters or muddy trails, keeping moisture out of your third brake light is critical to maintaining visibility and preventing electrical failures. The smoky finish also offers a distinct look that modernizes the classic boxy shape of these older trucks without being overly flashy.
However, you must be clear about what this product is not. It is a single unit count of one item. It does not replace the main taillights on either side of the vehicle, nor does it include bulbs. If your goal is to fix a broken left or right taillight, or if you are trying to upgrade the entire rear lighting package, this will not work for you. It is purely a high-mount stop light solution. Furthermore, while the installation is described as easy, the recommendation for professional installation suggests that if you are uncomfortable working with vehicle wiring or securing the unit tightly enough to maintain that foam seal, you might want to leave the job to a shop.

The OKLPF Rear Brake Tail serves a completely different purpose and targets a later generation of American pickup trucks. This product is designed specifically for the 2009 through 2014 Ford F-150 models. Unlike the single-unit nature of the PIT66, this listing covers a driver and passenger side unit count of two, meaning you get a complete pair to replace your existing left and right taillights. The design replaces the standard silver taillight assemblies with a red and chrome finish, offering a fresh aesthetic update for vehicles that may have faded or cracked over time.
Durability appears to be a central focus for the OKLPF design. The data indicates that these tail lights undergo multiple tests for temperature, humidity, dust, salt spray, and water. This level of testing implies a construction meant to withstand the rigors of daily driving and exposure to road salts, which is particularly relevant for SUV owners and truck enthusiasts living in regions where winter maintenance involves heavy salting. The inclusion of specific replacement part numbers like Bl3z13404ab and fo2819143 confirms that this is a direct-fit component designed to swap out the original equipment without needing custom modifications.
There is a significant caveat regarding body style compatibility that cannot be overlooked. The specifications explicitly state that these lights do not fit Flareside or Stepside configurations. They are intended for the standard bed versions of the F-150 during those model years. If you own an F-150 with a flared wheel well or a step side, this product will not align correctly with your body panels. Additionally, the packaging note clarifies that bulbs are not included, meaning you will need to source those separately if your old ones are burned out. The installation process is touted as simple and convenient with direct plug-and-play functionality, which is a major plus for DIYers who want to avoid cutting wires or splicing connectors.
• Best for Vehicle Compatibility → PIT66 LED 3rd for 1999-2007 GM trucks; OKLPF Rear Brake Tail for 2009-2014 Ford F-150 (Standard Bed).
• Best for Weather Resistance → PIT66 LED 3rd features high-density foam padding specifically for sealing out water and snow; OKLPF relies on multi-environment testing including salt spray and humidity resistance.
• Best for Complete Replacement → OKLPF Rear Brake Tail provides a driver and passenger pair for a full rear look; PIT66 is strictly a single third-brake-light upgrade.
• Best for Aesthetic Update → OKLPF offers a Red Chrome finish to refresh the rear of an F-150; PIT66 provides a Smoky finish for a modernized high-mount look on Silverados.
• Best for Installation Ease → OKLPF emphasizes direct plug-and-play convenience; PIT66 recommends professional installation to ensure proper sealing and alignment.
• Best for Specific Part Numbers → Both offer precise references (PIT66: 5978318/16525205; OKLPF: Bl3z13404ab series), but they apply to entirely different vehicle makes.
• Best for Durability Claims → OKLPF lists specific test types (dust, salt, water); PIT66 focuses on the physical seal and foam backing for leak prevention.
• Best Value for Older Trucks → PIT66 allows you to keep your original side lights while upgrading the center safety light; OKLPF requires swapping out both sides for a total overhaul.
In my opinion, the choice here is strictly dictated by your truck's year and make because these two parts simply do not overlap in application. I would recommend the PIT66 LED 3rd if you are an SUV owner or truck enthusiast restoring a late 90s or early 2000s GM vehicle, as the foam-sealed design offers peace of mind against the elements that older trucks often lack. Conversely, if you drive a mid-2010s Ford F-150, the OKLPF Rear Brake Tail is the logical choice because it solves the problem of aging, cracked taillights on both sides with a robust, tested assembly. Do not attempt to force either into the wrong vehicle; the difference in mounting points and electrical interfaces is too great. Check the current price on Amazon for whichever matches your specific model, and stick to the one that fits your body style perfectly.
The 2008 model introduced a new body style and likely different mounting points or part numbers that this unit does not support.
Yes, the product description explicitly states that bulbs are not included. You will need to source compatible bulbs separately to ensure your new taillights function properly upon installation.
No, the specifications clearly indicate that these lights do not fit Flareside or Stepside configurations. They are designed exclusively for the standard bed version of the 2009-2014 Ford F-150.
The PIT66 relies on a physical high-density foam pad and a sealed cover design to block water and mud, while the OKLPF claims durability through testing against temperature, humidity, dust, and salt spray. Both approaches aim for long-term reliability but use different engineering methods.
