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

LED bulbs for the front turn signal and DRL on the 2018-2026 Jeep JL Wrangler Sport S, Sahara and Rubicon and the 2020-2026 Gladiator. Each kit pairs a white bulb with an amber bulb so you get a brighter running light and a sharper turn signal.
Why it works
- Direct replacement for the factory incandescent bulbs, plug and play.
- Increased output with a modern LED look.
- Two brightness levels, built from Diode 7443 bulbs.
- Diode lists these Jeeps as needing a hyperblink fix (resistors or flasher) with LED turn bulbs, so plan for it.
Options
Stage 1 uses 7443 HP48 bulbs in white and amber, rated at 500 lumens. Stage 2 uses a 7443 XPR in white with a 7443 XP80 in amber, rated at 1,210 lumens. Both use the Cool White and Amber combination.
