The Diode Dynamics DD7986 is the Elite Series Type Y Fog Lamp kit in 3000K selective yellow, engineered to replace the factory fog lights on compatible Subaru vehicles with a bolt-in LED upgrade that produces up to five times more output than halogen. The DD7986 uses a custom-engineered patent-pending optic with multi-die automotive emitters and high-power full-copper circuit boards to generate an 80-degree-wide SAE F3-compliant fog beam pattern with an extremely sharp cutoff at the top edge to avoid glare. Each DD7986 lamp also includes an integrated amber accent backlight that illuminates the full lens housing when wired to a constant 12V source. The backlight shuts off automatically when the main fog beam activates. Installation is plug-and-play using factory connectors on compatible Subaru models. The DD7986 is engineered and assembled in the United States and backed by an 8-year warranty.

Diode Dynamics is a St. Louis, Missouri-based LED automotive lighting company founded in 2006. They engineer and assemble all Elite Series and Stage Series LED products in the USA using OEM-grade components, SAE-validated testing, and full in-house optical design. Diode Dynamics is recognized as a pioneer of the Elite Series performance fog lamp concept, which produces measurably higher output than any OEM or competing aftermarket fog lamp in its class.
The DD7986 is the Diode Dynamics Elite Series Type Y Fog Lamp in 3000K selective yellow, sold as a plug-and-play pair for compatible Subaru vehicles. The DD7986 uses a custom-engineered optic to produce an SAE F3-compliant 80-degree fog beam at up to five times the output of OEM halogen fog lamps, with an integrated amber backlight that activates when wired to a 12V constant source.
What is the difference between the DD7986 yellow and white versions?The DD7986 is the 3000K selective yellow version of the Diode Dynamics Elite Series fog lamp. The white version (sold under a different part number) outputs 6000K cool white. Yellow at 3000K filters blue-spectrum light that scatters in rain and fog, improving perceived road clarity in adverse weather. White provides higher raw brightness in clear conditions. Both versions share the same optic, housing, and SAE F3 fog beam pattern.
What Subaru vehicles does the DD7986 fit?The DD7986 fits the 2022-2025 Subaru WRX (GT, Limited, Premium, TR, TS trims), 2022-2024 Subaru Forester (Limited, Premium, Sport, Touring, Wilderness trims), 2023-2025 Subaru Ascent (Limited, Onyx Edition, Premium, Touring trims), 2024-2026 Subaru Crosstrek (all trims), and 2017-2020 Subaru BRZ (Limited, Premium, Series trims). Confirm your specific year and trim match before ordering.
Is the DD7986 truly plug-and-play?Yes. On compatible Subaru models, the DD7986 uses OEM-matched connectors that plug directly into the factory fog lamp wiring harness. No cutting, splicing, or external controller is required. The amber backlight uses a separate tap connector that connects to any 12V constant source for the desired function.
Does the DD7986 require any coding or module?No. The DD7986 is a direct electrical replacement for the factory fog lamp on compatible Subaru vehicles and requires no coding, module, or resistor on supported models. If your vehicle has factory LED fog lamps, confirm compatibility before purchasing.
What is the amber backlight on the DD7986 used for?The amber backlight on the DD7986 illuminates the full fog lamp lens housing in amber when wired to a 12V constant source. It can be used as a DRL accent, a parking light accent, or a running light depending on how it is wired. The backlight shuts off automatically when the main fog beam is activated.
How bright is the DD7986 compared to OEM fog lamps?Diode Dynamics rates the DD7986 at up to five times the output of OEM halogen fog lamps. In independent testing, the Elite Series yellow fog lamps measured approximately 580 maximum lux on-target, compared to 340 lux for OEM LED fog lamps and significantly less for halogen. The 80-degree beam width is also wider than most OEM and competing aftermarket fog lamps.
What warranty does the DD7986 carry?The DD7986 is backed by an 8-year limited warranty from Diode Dynamics: 3 years of full replacement warranty plus an additional 5 years of protection against manufacturing defects, for a total of 8 years from the date of purchase.
