The Diode Dynamics High Beam LED Headlight Bulb Pair for 1999-2018 Chevy Silverado from Nomadic Supply Company® delivers a true plug-and-play upgrade over factory halogen bulbs, bringing advanced TST LED technology and optimized optical focus to your Silverado’s high beam circuit. Engineered and designed in the USA, these bulbs are built for long-term reliability through rigorous environmental testing and backed by a limited lifetime warranty.
The Diode Dynamics High Beam LED Headlight Bulb Pair for 1999-2018 Chevy Silverado is available in two configurations — the SL2 Pro and the SL2 — giving Silverado owners the flexibility to choose between a fan-cooled, high-output option pushing 2,400 lumens per bulb or a fanless, 14-watt design with a copper-core circuit board and full-metal housing. Both variants share a fully integrated driver, meaning there are no external modules to mount or hide, and installation is as straightforward as swapping out the original halogen bulbs. With a 6000K color temperature and a beam pattern engineered to match the factory optics, the upgrade is immediately noticeable without introducing glare or irregular light distribution.
Durability is a cornerstone of the Diode Dynamics High Beam LED Headlight Bulb Pair for 1999-2018 Chevy Silverado, with each bulb tested through repeated thermal cycles ranging from -40°C to 85°C, validated against the SAE J575 Durability Test standard, and equipped with transient protection to guard against electrical spikes. Whether you select the SL2 Pro for maximum brightness or the SL2 for a compact, fanless solution, you can count on consistent, high-quality illumination mile after mile on your Silverado.
Diode Dynamics High Beam LED Headlight Bulb Pair for 1999-2018 Chevy Silverado Features:
- Direct Replacement: Serves as a direct replacement for Chevy Silverado High Beam headlight bulbs with compact fitment.
- Advanced LED Technology: Utilizes advanced LED technology for industry-leading performance.
- Internal Cooling: Features internal cooling for superior reliability.
- Compact Fitment with Integrated Driver: Compact fitment with an integrated driver keeps the installation clean and simple with no external components required.
- Limited Lifetime Warranty: Backed by a limited lifetime warranty for long-term peace of mind.
- Designed and Engineered in USA: Designed and engineered in the USA, with patents pending on the technology used.
- Next-Generation TST Technology: TST LEDs are designed with electrical connections on the top, dedicating the entire bottom surface to channeling thermal energy out and away from the LED, lowering thermal resistance and allowing higher power levels.
- Optimized Optical Focus: Engineered to focus light just like the factory Silverado bulb, matching the original beam pattern while providing an increase in total output. Uses optimized LED size to provide a smooth and comfortable beam pattern without streaks, lines, or harsh cutoffs.
- Internal Cooling (SL2 Pro): Features an integrated top-mounted fan sealed inside the housing, providing cooling right next to the LEDs. No concerns about damage from dust or moisture over time.
- Internal Cooling (SL2): Fanless design with a copper-core circuit board and thermally-optimized full-metal housing with integrated heatsink at 14 watts.
- Fully Integrated Design: No external drivers on either the SL2 or SL2 Pro. Plug-and-play connector — simply remove factory bulbs and install. SL2 Pro includes an adjustable collar that can be securely locked at the correct rotational position.
- Transient Protection: Includes transient protection to prevent premature failure from electrical spikes in the vehicle.
- Operating Voltage: Compatible up to 30V operating voltage.
- Environmental Testing: Tested through repeated thermal cycles from -40°C to 85°C (-40°F to 185°F) and a range of other environmental tests.
- SAE J575 Compliance: Meets the SAE J575 Durability Test compliance rating.
- These bulbs are a direct replacement for halogen headlight bulbs only and will not replace OEM HID bulbs.
