Upgrade. If you're looking to replace your factory yellowish incandescent bulbs and improve your visibility at night, you've probably found many options for LED upgrades. Most bulbs on the market are too big to install, don't work with the electrical system, and have no focus or hotspot in the beam pattern. Even if they come close on those aspects, they still aren't anything close to the quality you would find with factory-installed lighting. Like most aftermarket products, most LED bulbs are not engineered and tested for long-term reliability.
With the SLF LED, Diode Dynamics set out to engineer a true OEM-grade solution. With its compact size, optically correct output and boost-mode electrical circuit, the SLF LED is a properly-engineered solution that finally provides a true upgrade in performance, with high reliability: and it's tested and validated to meet those standards, just like OEM lighting.
Street Legal Output. Don't be fooled by high lumen numbers. Your vehicle's fog lights are designed to focus light. If the light source in the housing is out of focus, it doesn't matter how bright it is. You won't have a focused hotspot of light to shine down the road, you'll just have more glare. To correct this, the SLF LED bulb was engineered with advanced optical design software, which simulates each ray of light in a process known as "ray tracing." Using this tool, our engineers perfectly matched the filament location, allowing the SLF LED to focus light just like your original bulb, preserving the focus and hotspot, with no added glare. It produces a functional pattern on the road, with a stronger hotspot for added distance. This is a safe, functional output, in compliance with photometric standards, which we call Street Legal.
