Key Features & Benefits
Built for Select Peterbilt and Kenworth Applications
This chrome projector fog light is listed for the following applications based on the supplied product data:
- 2008-2020 Kenworth T660
- 2012-2021 Peterbilt 579
- 2012-2018 Peterbilt 587
Always confirm truck year, model, side requirement, wiring condition, and mounting area before ordering.
Chrome 4-1/4″ Round Projector Fog Light Design
The 4-1/4″ round projector fog light uses a chrome finish for a brighter, polished appearance. This makes it a strong option for trucks with chrome bumpers, polished trim, stainless accessories, or a cleaner show-style front-end setup.
Aluminum Die-Cast Housing
The aluminum die-cast housing gives this fog light a rugged structure for heavy-duty truck use. This is a verified housing feature and helps separate this product from lighter-duty replacement lighting.
Single High Power Primary LED
This fog light uses a single high power primary function LED for the main fog light output. The supplied product data lists the output at 800 lumens.
8 Additional LEDs as Position Lights
This light includes 8 additional LEDs as position lights. The position lights require wiring with a standalone wire lead with male bullet plug, so buyers should plan for that added wiring step if they want the position light function active.
OEM-Style Mounting Bracket
The OEM-style mounting bracket supports a straightforward installation path for the listed truck applications. Always inspect the existing mounting area and hardware condition before installation.
OE-Style Wiring Harness
This fog light uses an OE-style wiring harness for the main electrical connection. The position light function requires a separate wire lead with male bullet plug, so wiring should be checked carefully before installation.
800 Lumen Output
This fog light is rated at 800 lumens based on the supplied product data. Avoid comparing output against other fog lights unless verified testing data is available for both products.
12V DC Only
This fog light is designed for 12V DC systems only. Do not use this product on a different voltage system unless compatibility is confirmed by the supplier or product documentation.
DOT/SAE, FMVSS 108, and IP67 Rated
The supplied product data lists DOT/SAE, FMVSS 108, and IP67 rating for this fog light. Confirm product labeling and local requirements before installation if compliance is important for your application.
Performance / Compatibility / Use Case
Best Use: Chrome Projector Fog Light Replacement With Position Lights
This product is best used as a chrome projector fog light replacement or upgrade for listed Peterbilt and Kenworth applications. It is suited for truck owners who want fog light function plus integrated LED position lights in a round chrome housing.
Chrome vs Black Version
Choose the chrome version if you want a brighter polished look that matches chrome bumpers, stainless trim, and exterior accessories. Choose the black version if you want a darker blackout-style appearance. Both versions should still be selected by verified application, side needs, and quantity.
Different From the 18 LED Version
This 9 LED version uses a single high power primary function LED with 8 additional LEDs as position lights and is 12V DC only. The 18 LED version uses 6 high power CREE-type LEDs with 12 additional position light LEDs and may have different voltage compatibility, fitment notes, and ratings depending on the exact SKU.

- 2008-2020 Kenworth T660
- 2012-2021 Peterbilt 579

Do not assume fitment beyond those applications unless confirmed by supplier data.
Installation / Fitment / Technical Details
