Diode Dynamics set the standard for LED bulbs in 2017, with the introduction of the SL1 LED. The SL1 was the first bulb engineered to provide a true increase in performance. After many years, and thanks to improvements in technology, we are excited to introduce its successor: the SL2 Pro! The new SL2 Pro LED has been carefully refined and improved with some major upgrades: next-generation TST LED technology, an integrated top-mount fan, and a fully-integrated, wire-free design. As a direct plug-and-play replacement, it provides a significant increase in output, in a compact package.
Next-Generation TST Technology. The SL2 Pro features new thermal separation technology (TST) LEDs. Unlike a traditional LED chip, TST LEDs are designed with electrical connections on the top. This means the entire bottom surface of the LED can be dedicated to channeling thermal energy out and away from the LED. This lowers thermal resistance, allowing the SL2 Pro to run at higher power levels than traditional LED bulbs, while maintaining focus.
Optimized Optical Focus. The headlight housings on your Dodge Challenger are designed to focus light. If the light source in the housing is out of focus, it doesn't matter how bright the bulb is - you won't have a focused hotspot of light to shine down the road where you need it. Instead, you'll have more glare, which lights up the foreground and makes it harder to see in the distance. The SL2 Pro LED bulb was engineered to focus light just like your Challenger's original bulb, matching the original beam pattern while still providing an increase in total output. These days, some LED bulbs on the market use the smallest LEDs possible to accomplish focus, but this leads to "over-focus", where you begin seeing streaks, lines, and harsh cutoffs in the beam pattern. Instead of using the smallest LEDs possible, the SL2 Pro was optimized to provide a smooth and comfortable beam pattern, while still maintaining focus and increased output.
Internal Cooling. The SL2 Pro features an integrated top-mounted fan for superior thermal management and reliability. Since the fan is sealed inside the housing, there's no concerns about damage from dust or moisture over time. And with the fan on the top of the bulb, the cooling happens right next to the LEDs - the source of the heat. While standard LED bulbs use heat pipes and other tricks to move heat to the bottom of the bulb, where it's cooled off, the SL2 Pro keeps it simple and more efficient. This provides maximum cooling efficiency and output.
Fully Integrated Design. Unlike traditional LED bulbs, the SL2 Pro LED bulb doesn't have any extra wires or external drivers. Along with its compact size, that means excellent fitment inside your Challenger's housing, without the need to tuck away wiring or bulky drivers. Installation is easy - simply remove your factory bulbs and the SL2 Pro will fit in its place, with a plug-and-play connector. And if your original bulb is installed at an angle, no worries - SL2 Pro has you covered with an adjustable collar that can be securely locked at the correct position. For specific fitment information, please see Vehicle-Specific product listings, or contact us.
Reliability. Every part of the SL2 Pro LED was engineered for reliability, from its full metal construction to the fully-sealed design. The SL2 Pro was put through its paces in our environmental testing chambers - where the bulb lasted through repeated thermal cycles from -40 through 85 degrees Celsius (-40 to 185F), along with a range of other environmental tests. It's also designed with transient protection, to prevent premature failure from electrical spikes in the vehicle. It's even compatible up to 30V! We're so confident in the SL2 Pro, that it's backed by an industry-leading limited LIFETIME warranty. See details at diodedynamics.com/warranty.

Additional Notes
This product is not DOT compliant for use in headlamps on public roads in the United States.
Within the United States, most automotive lighting equipment is regulated by the U.S. Department of Transportation (DOT). Lighting equipment that is regulated by DOT must comply with Federal Motor Vehicle Safety Standard (FMVSS) 108, in order to be used legally on public roads.
Headlights and headlight bulbs are regulated by DOT, and must comply with the requirements of FMVSS108. There is currently no provision within these regulations to legally replace halogen headlamp bulbs with retrofit LED bulb replacements. As a result, retrofit LED bulbs may not be used in headlights on public roads in the United States.
Fog lamps and fog light bulbs are not regulated by federal safety standards. When used in compliance with any applicable state or local laws, LED fog light bulbs are considered street-legal for use in the United States.
Based on these regulations, headlamp retrofit LED bulbs are not available for purchase from Diode Dynamics for street use in the United States. We recognize that certain vehicles can be used exclusively off of public roads (off-street), for recreational, utility, or transport purposes. In the United States, only vehicles that are exclusively used off-street may purchase and use LED headlamp retrofit bulbs from Diode Dynamics.
Only vehicles which are strictly and exclusively limited to off-street use qualify as off-street vehicles. Mixed use (sometimes driven on public roads, and sometimes driven off-street) do not qualify as off-street use vehicles. If a vehicle is driven on public roads at all, the vehicle does not qualify as off-street use. If the vehicle has registration and license plates, it would not be considered an off-street use vehicle. Please review the following vehicle uses and permissible use of LED retrofit headlight bulbs:
Fog Lights: Bulbs not regulated by DOT. Street Legal, depending on state and local laws.
Street Vehicle Headlights (registered, used on public roads): Headlight bulbs regulated by DOT. Not legal for sale or use in the United States.
Mixed-Use Vehicle Headlights (registered, some use on public roads): Headlight bulbs regulated by DOT. Not legal for sale or use in the United States.
Off-Street Use ATV/UTV: Not regulated by DOT. Legal for sale and use.
Off-Street Use Snowmobile: Not regulated by DOT. Legal for sale and use.
Off-Street Use Agricultural Equipment: Not regulated by DOT. Legal for sale and use.
Off-Street Use Construction Equipment: Not regulated by DOT. Legal for sale and use.
Off-Street Use Racing Vehicle: Not regulated by DOT. Legal for sale and use.
Diode Dynamics makes products available for sale internationally. International customers should consult their own laws and regulations before purchase, to determine the appropriate and proper use of LED bulbs within their region.
