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 Stage Series 10-pin Dual-Output Trailer Wiring Harness lets you run two Diode Dynamics LED pods with backlight functionality straight off your truck’s 10-pin trailer hitch wiring. It ends in two Deutsch DT outputs, so the pods plug in without splicing into the vehicle harness, and the lights work along with the signals your truck already sends to a trailer.

Why it works

Hitch-mounted pods are only useful if they come on when you need them without a dedicated switch you forget about. Tapping the trailer connector gives you simple, everyday operation: the pods respond to the same circuits a trailer would. The high-capacity 14AWG wiring feeds both outputs, and the harness supports pods with backlight functionality. It is rated from -40°F to 185°F, so a Wisconsin winter is not a concern.

Options

Single-output harnesses run one pod; dual-output harnesses split to two. This one has two Deutsch DT outputs. Match the 10-pin connector to what your hitch wiring uses before ordering.

Fitment

Universal for vehicles with a 10-pin trailer connector. It operates on 9–16V, which covers standard 12V truck systems.
