SL1 LED Headlight for 2008-2009 Pontiac G8​


Diode Dynamics is pleased to offer the USA-made SL1 LED Headlight bulbs for 2008-2009 Pontiac G8

If you're looking to improve your 2008-2009 Pontiac G8’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 2008-2009 Pontiac G8’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. 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 2008-2009 Pontiac G8, 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 2008-2009 Pontiac G8, for years, and is backed by a three-year warranty.

LED Focus: What you need to know!


Are you looking to make the switch from halogen to LED headlight bulbs? Before you do, check out this video to ensure you choose the best one.

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!

Love my SL1s and SLFs. Haven't done the high beams yet tho.

FWIW, I was not able to fit the stock dust cap over my SL1s on the low beam. I was told it should fit, but no dice for me. I found an extended dust cap on Amazon to accommodate it.

I also put them on my wife's Volt. Those did fit with the stock cap.

I have the SL1 low beam leds. They did fit inside headlight housing and I was able to replace (re-attach) dust covers. They have a razor sharp cut off line. I am quite pleased with these. You don't have to 'screw around ' with adustment screws or rotate bulb etc that I have seen on other brands. These are a good plug and play to update your look. I know, 'fitted custom projectors with hid's are best'. These are a good alternative. Just noticed, I have to change my sig.

I'm glad to hear it! And thank you for the feedback, I'm sorry if there was any confusion on our end.

I'll be sure to let our support team know about your experience with the dust caps.

Thanks for your support! They're a great solution for improving visibility without having to wire, splice, or open your headlights.

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!
