1,800-Lumen H7 TST LED Upgrade with Lifetime Warranty for Fog and DRL Applications
The Diode Dynamics DD0484P is the H7 SL2 Pro LED bulb in 6000K cool white, sold as a pair. The DD0484P uses Diode Dynamics' TST (Thermal Stabilized Technology) automotive-grade LED emitter on a full-copper PCB inside a die-cast A360 aluminum housing with an integrated top-mounted cooling fan for active heat management. Each bulb delivers 1,800 steady lumens at 15.4 watts, uses the same OEM H7 connector for plug-and-play installation, and operates across a wide 9-30V range for compatibility with 12V automotive and 24V commercial applications. The DD0484P is legal for fog light and DRL use in the USA. Headlight use is not DOT-compliant in halogen housings. Diode Dynamics backs the DD0484P with a limited lifetime warranty and a 30-day no-restocking-fee return policy.
Key Features
- 1,800 Lumens per Bulb: The DD0484P delivers 1,800 steady lumens per bulb, with correct optical focus designed to replicate the OEM H7 filament position for a controlled beam pattern in fog light and DRL housings
- TST Automotive Grade LED: The DD0484P uses Diode Dynamics' proprietary TST (Thermal Stabilized Technology) LED emitter with superior thermal efficiency, reducing lumen depreciation over time versus competing LED emitters
- Integrated Active Cooling: A top-mounted cooling fan inside the DD0484P housing actively manages thermal output for consistent lumen output during extended operation without requiring external heat sinks
- Full-Copper PCB Construction: The copper printed circuit board in the DD0484P transfers heat away from the LED junction faster than aluminum-substrate alternatives, extending LED service life
- 9-30V Wide Voltage Range: The DD0484P operates across 9 to 30 volts, making it compatible with both 12V passenger car systems and 24V commercial vehicle applications
- OEM H7 Plug-and-Play Connector: The DD0484P uses an OEM-matched H7 connector and compact housing designed to fit in tight fog light and DRL housings without modification on compatible vehicles
- Limited Lifetime Warranty: Diode Dynamics backs the DD0484P with a limited lifetime warranty against defects in materials and workmanship

Frequently Asked Questions
What is the Diode Dynamics DD0484P?The DD0484P is the Diode Dynamics H7 SL2 Pro LED bulb kit in 6000K cool white, sold as a pair of two bulbs. Each bulb delivers 1,800 lumens at 15.4 watts using TST automotive-grade LED technology with an integrated cooling fan and full-copper PCB. The DD0484P is plug-and-play for H7 fog light and DRL applications and is backed by a limited lifetime warranty.
Is the DD0484P legal for headlight use?No. Diode Dynamics explicitly states the DD0484P is legal for fog light and DRL use in the USA only. It is not DOT/FMVSS108 compliant for headlight use in halogen reflector or projector housings. Using it in headlight applications on public roads may not be legal in your state. Verify your local laws before installation.
Does the DD0484P fit without modification?Yes. The DD0484P uses an OEM-matched H7 connector and compact housing that is designed to install without modification in most H7 fog light and DRL housings on compatible vehicles. Verify your specific vehicle's fog light housing depth and clearance before ordering, as some vehicles have tight housings that may require adapter collars (sold separately by Diode Dynamics).
What voltage range does the DD0484P operate at?The DD0484P operates across 9 to 30V, covering standard 12V automotive applications as well as 24V commercial vehicle applications. The internal driver maintains constant current output across this voltage range.
How does the DD0484P compare to the SL2 (non-Pro)?The DD0484P SL2 Pro produces 1,800 lumens per bulb versus 1,400 lumens for the standard H7 SL2. The Pro also uses the TST LED emitter and active cooling fan for superior thermal management. The standard SL2 uses a passive heatsink and different emitter. Both carry a lifetime warranty.
Does the DD0484P work as a DRL?Yes. The DD0484P operates at full brightness when used in a DRL circuit. No separate DRL harness or controller is required on compatible vehicles where the factory H7 DRL operates through the same socket as the fog light.
What is the cooling method on the DD0484P?The DD0484P uses an integrated top-mounted active cooling fan inside the aluminum housing. The fan draws heat away from the LED and PCB, maintaining stable operating temperatures during extended on-time to prevent lumen depreciation and premature failure.
What warranty does the DD0484P carry?The DD0484P is backed by a Diode Dynamics limited lifetime warranty against defects in materials and workmanship, plus a 30-day return policy with no restocking fee.
Installation Instructions
- Confirm the DD0484P matches your vehicle's fog light or DRL bulb size (H7) before proceeding. Do not install in headlight sockets
- Turn off the vehicle and allow all lights to cool fully before handling bulbs
- Access the fog light housing from behind the bumper or through the wheel well liner, depending on your vehicle's design
- Disconnect the OEM H7 bulb connector and remove the factory halogen bulb by rotating counterclockwise and pulling straight out
- Handle the DD0484P bulb by its base only. Do not touch the lens or LED emitter surface
- Insert the DD0484P into the fog light socket, align the retaining tabs, and rotate clockwise to lock. Connect the OEM wiring harness to the DD0484P connector until it clicks
- Repeat on the opposite side
- Power on the fog lights and verify both DD0484P bulbs illuminate. Confirm beam pattern is correctly aimed per your vehicle's fog light aim adjustment if applicable
