Diode Dynamics is excited to announce our SL1 LED Headlight Bulbs are now in stock for all bulb sizes!  For any vehicle using H8, H9, H10, H11, 9005, 9006, and 9012 size headlight bulbs, the SL1 is the #1 headlight bulb upgrade!

So what makes the SL1 better than the rest? Optically designed to be more focused than any other LED on the market, the SL1 shines more light down the road with no added glare. They’re also tested to OEM standards, and engineered with more expensive OEM-grade features to assure quality, and built here in USA. In short, the SL1 is designed, tested, and built to a much higher standard than your average imported bulb.

✅ Street Legal output: The SL1 LED utilizes six Luxeon ZES chips to mimic the filament and output of a factory halogen headlight bulb. This reduces glare in reflector and projector housings and produces beam patterns with a more intense, focused light on the road.

✅ Better visibility: Designed for both projector and reflector headlights, the SL1 delivers a lab-verified 1630 lumens per bulb, a dramatic upgrade from your stock lighting!

✅ Plug-and-play: With its patented compact design, the SL1 LED fits where larger, generic LED bulbs won’t. The SL1 also plugs directly into your vehicle’s stock headlight harness, there is NO modification needed! 

✅ Long lifespan:  The SL1 features a dust and water-resistant side MagLev Sunon Fan, specifically-designed heat sink fins, and copper PCB core to ensure maximum heat transfer and an extremely long lifespan.

✅ Made in USA: The SL1 has been fully designed, tested, and manufactured right here In St. Louis, Missouri!
