Factory Fog Lamp Upgrade Done Right: DD8289 SSC1 White LED Fog Kit for the Toyota GR Corolla
The Diode Dynamics SSC1 LED Fog Light Kit is a purpose-built, plug-and-play replacement for the factory fog lamps on the 2023-2025 Toyota GR Corolla. Designed around Diode Dynamics' Stage Series SSC1 LED pods, the DD8289 delivers 430 lumens of white 6000K output through a custom-engineered TIR optic that collects and directs every lumen onto the road with no wasted light or glare.
The kit includes Foxbeam Type BM vehicle-specific brackets that drop the SSC1 pods directly into the factory fog lamp location for a clean OEM-style appearance, with no drilling or modification needed. Factory 4-pin DT to DJ70 wiring adapters are included so the DD8289 connects directly to the factory fog wiring harness using T-tap connectors, maintaining full plug-and-play compatibility.
When installed as a pair and aimed per your state's regulations, the DD8289 meets SAE J583 fog lamp standards for road-legal use. The included amber backlight illuminates the full TIR optic lens as an accent light for a distinctive look. Engineered and assembled in the USA.

Frequently Asked Questions
What is the DD8289?
The DD8289 is the Diode Dynamics SSC1 LED Fog Light Kit for the 2023-2025 Toyota GR Corolla in White SAE Fog output. It replaces the factory fog lamps with 430-lumen SSC1 LED pods using Foxbeam Type BM vehicle-specific brackets and plug-and-play factory wiring adapters, meeting SAE J583 standards for road-legal fog use.
What years and trims does the DD8289 fit?
The DD8289 fits the 2023-2025 Toyota GR Corolla in Core, Circuit Edition, Morizo Edition, and Premium trims. Verify your exact model year and trim before ordering.
Is the DD8289 plug-and-play on the GR Corolla?
Yes. The DD8289 includes Foxbeam Type BM vehicle-specific brackets and 4-pin DT to DJ70 wiring adapters with T-tap connectors that connect directly to the GR Corolla's factory fog wiring. No cutting, soldering, or additional wiring is required.
Is the DD8289 road-legal?
Yes. When installed as a pair and aimed per your state's regulations, the DD8289 meets SAE J583 standards as a road-legal fog lamp. It is not designed for use as a driving or auxiliary off-road light.
What does the amber backlight on the DD8289 do?
The DD8289 SSC1 pod includes a backlight feature that illuminates the entire TIR optic lens in amber as an accent light. This is a cosmetic accent feature and is separate from the white fog output function.
What is the waterproof rating on the DD8289?
The DD8289 SSC1 pods are rated IP69K, meaning they are protected against high-pressure, high-temperature water jets from all directions, making them fully sealed for all weather conditions.
How does the DD8289 TIR optic compare to a standard reflector?
Standard reflectors and simple lenses lose light to glare and internal scatter. The DD8289's custom-engineered TIR optic collects all LED output and directs it precisely to the target zone, dramatically reducing glare and improving usable road illumination.
Where is the DD8289 made?
The DD8289 is engineered and assembled in the USA by Diode Dynamics at their facility in St. Louis, Missouri.
