Vendor warranty summary

Diode Dynamics Warranty

At a glance: 3 years on every Diode Dynamics product, 8 years on Stage Series and Elite Series lamps, and lifetime coverage on Stage Series pods, rock lights, SL2 bulbs and off-road brackets (orders from April 15, 2025)

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
Commercial or industrial use (construction, mining, fleet, agriculture and similar) Capped at 8 years
Form Lighting products (a Diode Dynamics brand) 2 years (details)

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

The Diode Dynamics D-Switch is an 8-channel switch panel for running all your auxiliary lighting and accessories from one place. It pairs a compact controller with a separate solid-state hub, adds a Bluetooth app, a dedicated backlight channel and three trigger wires for factory-style control off vehicle signals. It is universal for trucks and SUVs.

Why it works

Once you have a light bar, ditch lights, rock lights and a compressor, the dash runs out of room for switches. The D-Switch puts eight channels on one controller and lets you group outputs, so one button can fire several things at once. The hub is solid-state and fully encapsulated, with an IP67 rating and a pin-fin heatsink, and it is rated from -40F to 250F. The three trigger wires let the vehicle's own signals switch a channel for factory-style operation. The Bluetooth app is quick to respond. It is engineered and assembled in the USA.

Channels

  • Channels 1-4: 15A each
  • Channels 5-8: 30A each
  • Backlight channel: 15A total
  • Maximum total current: 125A
