Diode Dynamics, a trailblazer in LED bulb technology. Now, building upon that legacy, they proudly present the SL2 Pro, the next evolution in automotive lighting. Designed to elevate your driving experience, the SL2 Pro combines cutting-edge features with exceptional performance.

The SL2 Pro features next-generation TST (Thermal Separation Technology) LEDs. Unlike conventional LED chips, TST LEDs have electrical connections on the top surface. This unique design allows the entire bottom area of the LED to efficiently dissipate thermal energy, resulting in lower thermal resistance. With improved heat management, the SL2 Pro can operate at higher power levels without compromising focus or longevity.

Additionally, the SL2 Pro incorporates an integrated top-mount fan that efficiently dissipates heat. Say goodbye to overheating and hello to consistent brightness. Your vehicle’s housings are designed to focus light, and the SL2 Pro was engineered to match the original beam pattern while still providing an increase in total output. Unlike some LED bulbs on the market that sacrifice focus for brightness, the SL2 Pro maintains a smooth and comfortable beam pattern.

Upgrade your lighting game with the Diode Dynamics LS2 Pro LED bulbs. Experience enhanced visibility, reliability, and style all in a compact package. Whether you’re navigating city streets or conquering off-road trails, the SL2 Pro is your trusted companion for safer and more enjoyable driving.

Limited Lifetime Warranty
In addition 3-Year and 8-Year Replacement Limited Warranties, Diode Dynamics carries a Lifetime Limited Warranty on select products. Currently, this includes and is limited to SL2 and SL2 Pro LED Bulbs. Please reference product detail pages to determine the specific warranty terms of each product.

After 3 years of Replacement Limited Warranty, Diode Dynamics will warrant that select products will be free from defects in material and workmanship, subject to exceptions, limitations, and stipulations. Generally, the Lifetime Limited Warranty only applies to functional and product failure, and does not cover cosmetic characteristics of the product. See exceptions, limitations, and stipulations below.

If you have an issue with any product, we will diagnose the issue with you, and you may be required to answer questions or assist in the diagnosis. If Diode Dynamics determines that your product is defective in material or workmanship, Diode Dynamics will issue an RMA number. An RMA number must be issued before any items are returned.

If a defect is found beyond the initial 3 years of Replacement Limited Warranty, products must be returned at the customer's expense to Diode Dynamics for inspection, and will be replaced or repaired, at the sole discretion of Diode Dynamics. For U.S. customers, shipping back to the customer will be covered by Diode Dynamics. International customers are responsible for all shipping costs.

Exceptions, Limitations, and Stipulations
Terms: Warranty terms, policies, and limitations are subject to change without notice.

Proof of Purchase: Proof of purchase is required for any warranty request.

Transferability: Warranty coverage is extended only to the original purchaser of the products, and is not transferable. If a product is purchased as a gift, the recipient may claim warranty coverage even if they do not have proof of purchase, by registering for warranty within 90 days of the original purchase date.

Timing: All warranty coverage periods are based on the number of days between original purchase date from Diode Dynamics or its authorized dealer in good standing, and the date of submission of an RMA Request (warranty service request) by Diode Dynamics.

Use: When products are used in a commercial or industrial setting, any warranty coverage exceeding the initial 3-year Limited Replacement Warranty is not valid. This includes, without limitation, construction, mining, manufacturing, forestry, commercial flight, and agriculture.

Surface Finish: Many Diode Dynamics products feature treated surfaces, with paint, powdercoating, anodization, UV coating, etc. These coatings, while durable, are not designed to last indefinitely, and wear out over time depending on use. To prolong lifespan, we recommend that products are shielded from UV light when possible, cleaned regularly using mild detergents, and that they are not subjected to abrasives or damage. Surface finishes that wear out from regular wear and tear are not covered under warranty. If damage in coatings appears within the initial 3 Year Replacement Limited Warranty, and is determined to be caused by manufacturing defect, it will be covered or repaired. Surface finish issues are not covered under any other warranty terms, for any reason.

Condensation: Certain products from Diode Dynamics contain sealed volumes of air. High-power LEDs create a large amount of heat, so the air expands and contracts as the lamp heats up and cools down. Pressure-equalizing vents are used whenever possible to prevent damage to the seal of the lamp, but this can occasionally introduce moisture in the air, especially with high humidity. Under certain circumstances, condensation may collect on the outside lens of the product, as it is much cooler than the rest of the lamp. This condensation is normal, and not covered under warranty. Condensation can be removed by allowing the lamp to fully warm up, or reducing outside humidity. If moisture buildup becomes greater than simple condensation, this indicates an issue with the product seal, and Diode Dynamics will cover it under warranty, in its sole determination. When making warranty claims for moisture buildup, we encourage you to include photographs showing the extent of the moisture.

Components: If a problem exists with a single component, Diode Dynamics may replace only the component needed to restore function.

Installation and Labor: Diode Dynamics product warranties are limited to coverage of products only. Diode Dynamics does not warranty or offer compensation or coverage of installation labor or time that may be required for replacement of warranty items. We strongly encourage customers to contact us prior to seeking outside assistance in diagnosis of any product issue.

All warranties, expressed or implied, are void if our warranty claim department determines that there is sufficient evidence of one or more of the following:

Negligence: Improper installation or improper use, including using or installing any product in a manner not specified by Diode Dynamics, or damage caused by improper installation.
Abuse: Damage beyond the limits of "normal wear and tear."
Product Modifications or Repair: See below.
Unauthorized Dealer Purchase: Purchase of items through any unauthorized party. We encourage you to contact Diode Dynamics prior to purchase to verify the seller is authorized.

Product Modifications
We understand that some products may be modified in the course of installation or use by the customer to suit a particular need. However, opening, disassembling, cutting wires, attempting repair, or otherwise modifying any product in a manner not specified by Diode Dynamics will void the product warranty, subject to the exclusions below.

For modifications to wiring, electrical components, or connectors, our staff will assist as possible, but is trained to support problems that arise in the course of standard use, without modification. Product instructions and installation guidance should be followed as written, and products should not be modified.

Exclusions: Replacing lenses on products where they are marketed as "replaceable," such as Stage Series LEDs, will void the 3-year limited replacement warranty. However, the 8-year limited warranty will be upheld and in effect. In the case of moisture intrusion for serviceable lamps, you may be required to open and re-seal the lamp yourself. If issues persist, we may require that the lightbar or LED pod is returned for repair under warranty.
