SL1 LED Headlight Bulbs for 2001-2016 Lexus IS Sedan


Diode Dynamics is pleased to offer the USA-made SL1 LED Headlight bulbs for Headlight for 2001-2016 Lexus IS Sedan

If you're looking to improve your 2001-2016 Lexus IS Sedan’s visibility at night, you've probably seen plenty of aftermarket LED headlight bulb options. There are plenty of “high performance” LED lights 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, Diode Dynamics SL1 LED Headlight Bulbs are truly the best LED headlight bulbs on the market.

Street Legal Output. Don't be fooled by high lumen numbers or "projector specific" bulbs. Your 2001-2016 Lexus IS Sedan’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, the 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 might’ve seen led headlight kits that use large straps for cooling, or fans that just make noise. These light 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 micro fan. The result is a highly effective and reliable cooling system, keeping the SL1’s LED chips running at maximum potential.


Fitment. With its patented design, installing the SL1 LED headlight bulb is simple and straightforward, requiring NO cutting or modification. There's no hanging metal straps, just a compact bulb that plugs right into your 2001-2016 Lexus IS Sedan, 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 specifically to fit your vehicle, 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 2001-2016 Lexus IS Sedan for years, and is backed by a three-year warranty.

LED Focus: What you need to know!


Good optical focus means more light further down the road where you need without any glare. We put together this video to highlight what to look for when choosing an LED headlight bulb for your vehicle. Check it out! And don't forget to shoot us a PM for free USPS shipping on any U.S order!

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

the hyperlinks in your first post dont work. although my work may be blocking the site.

do you have an actual comparison between a stock 1IS head light and one installed with a LED one?

Sorry about that! It seems that the image links are working, but we're having issues with a few of the model year-specific links in the text. In the meantime, you can check out everything for your vehicle through our Vehicle Finder tool (you might just have to copy-and-paste): https://www.diodedynamics.com/by-vehicle.html

And that's a great question. We're bringing in new models for SL1 media shoots on a weekly basis, so I'm hoping to have some Lexus-specific comparison images very soon.

the links were more or less a heads up. ill wait till i actually see some compassion shots on an is300. ive seen aftermarket stuff in other applications and the light output is usually way worse than just sticking with stock.

with that being said, none of what i have seen is your product. which is why im curious. :)

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!​

Definitely!

I'll keep an eye out for some relevant images, and post up as soon as I have some.

Thanks!

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!
