Our SL1 LED Headlight Bulbs were built to last. And we've done the testing to prove it. Check out a behind-the-scenes look into our lab where we conduct thermal, vibration, and electrical testing to ensure years of reliable performance without flickering or failure!

Measuring Headlight Output | Diode Dynamics

How are headlight output patterns measured at the factory level? How do you test to see if a headlight is meeting SAE and DOT beam pattern requirements? Here at Diode Dynamics, we've invested in a goniometer to accurately measure and map the entire beam pattern and ensure our products are adding light output without adding extra glare.

Check out the video to see how it works!

How hot an LED headlight bulb gets has a BIG impact on how bright it will be over time and how long it will last. Check out this video to see if your headlights are getting too hot!

Think having LED headlight bulbs shine light 360-degrees is a good idea? Think again! Check out this video to see why!

SL1 LED Headlight for Dodge Ram

Diode Dynamics is pleased to offer the USA-made SL1 LED headlight for Dodge Ram applications.

SL1 LED Headlight. If you're looking to improve your visibility at night, you've probably seen many options available for LED upgrades. There's plenty of LED bulbs on the market, but they all have their shortcomings. They're too big to install, have no hotspot in the beam pattern, or they simply stop working after just a few months. With its compact size, optically correct output, thermally-modeled cooling, and boost-mode electrical circuit, the SL1 LED finally provides a true upgrade in performance.

Street Legal Output. Don't be fooled by high lumen numbers or "projector specific" bulbs. Your Ram’s headlights are designed to focus light. If the light source 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 - just more glare. Some generic options have such a poor optical design, they might leave you wondering “how are LED headlights legal?!”

To correct this, Diode Dynamics' SL1 LED Headlight Bulb was engineered with advanced optical design software, to perfectly match the halogen filament location. This allows the SL1 to focus light just like the original halogen headlights, preserving the focus and hotspot, with no added glare. It produces a functional beam pattern with zero glare, which we call Street Legal.

Tested to Perform. We test the SL1 in factory car headlights and measure the entire beam pattern using specialized equipment. The entire beam pattern is mapped, and we compare the total output to the original equipment, confirming that the SL1 headlight bulb shines more light in the hotspot, without adding extra glare on the road. The test results speak for themselves: in most lamps, there is 30-70% more light output in the critical hotspot, with zero glare. Thanks to optical engineering, testing, and validation in the application, the SL1 is the #1 LED headlight bulb for reflector and projector headlights.

Staying Cool. You may have seen bulbs that use large straps for cooling, or fans that just make noise. These bulbs run hot, resulting in degradation of output after a few months. When it comes to cooling, proper engineering is required to efficiently remove heat from the bulb. In the SL1, a copper core board, thermal phase-change material, and thermally-modeled zinc casting get heat to the base, where base fins release it, designed for aerodynamic performance in conjunction with the flow rate and pressure of the Sunon bearingless microfan. The result is a highly-effective and reliable cooling system, keeping the bulb running at maximum potential.

Fitment. With its patent-pending design, the SL1 LED fits where other bulbs won't, without cutting or modification. There's no hanging metal straps, just a compact bulb that plugs right in, with a nylon-reinforced shroud. Only slightly larger than a standard halogen bulb, it fits behind dust caps and in tight spaces. The base sizes are keyed for exact applications, not one-size-fits-all, and the compact driver easily tucks away.

Reliability. Every part of the Diode Dynamics' SL1 LED Headlight Bulb is engineered with more expensive OEM-grade features to assure quality, such as the Sunon MagLev fan and PCB wire connectors" In short, these are designed, tested, and built to a much higher standard than your average imported led headlight conversion kit. The Diode Dynamics' SL1 LED Headlight Bulb will keep performing in your Ram truck for years, and is backed by a three-year warranty.
