This is Diode Dynamics' policy, not an NVMOS policy. We've summarized Diode Dynamics' published warranty in plain English. The manufacturer's official terms always govern and can change without notice. Last reviewed on nvmos.com: October 15, 2026.
Coverage by product
| Product or component | Coverage |
|---|---|
| All Diode Dynamics products: defects in materials and workmanship | 3 years |
| Stage Series and Elite Series lamp assemblies and lamp mounting brackets (functional failure; wiring, harnesses and lens covers excluded after year 3) | 8 years |
| Stage Series LED pods, Stage Series rock lights, SL2 and SL2 Pro LED bulbs, off-road mounting brackets, ordered on or after April 15, 2025 (functional failure after year 3) | Lifetime |

What's covered
- Defective products are replaced with the same item, or a comparable one if it's been discontinued
- Diode Dynamics may replace just the failed component
- Finish defects caused by manufacturing, during the first 3 years
- Moisture beyond normal condensation that points to a seal failure, at Diode Dynamics' discretion
- Free tech support for the life of the product, even after the warranty ends
What's not covered
- Normal condensation, and paint or coating wear from regular use
- Installation or labor costs
- Improper installation or use, abuse, or opening, rewiring or repairing a product
- Swapping lenses on Stage Series lights voids the 3-year coverage (the 8-year coverage stays)
- Purchases from unauthorized sellers; coverage is for the original buyer and isn't transferable
How to make a Diode Dynamics claim
- Keep your proof of purchase; every claim needs it (gift recipients can register within 90 days of the original purchase instead)
- Request an RMA through Diode Dynamics' returns portal and work through diagnosis with their support team
- Nothing goes back without an RMA number; include photos for moisture claims
- For US customers, Diode Dynamics covers shipping on 3-year claims, plus return shipping for inspection on 8-year and lifetime claims
