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

Diode Dynamics XP80 3156/3157 turn signal LED bulbs are a direct replacement for factory incandescent 3156/3157-size turn signal bulbs, front or rear. They produce 510 lumens per bulb, give your signals a crisp LED look, and plug straight into the factory socket.
Why it works
Each bulb arranges sixteen high-power LEDs in all directions on a metal heatsink, driven by an inductive constant-current circuit to hold output steady. Electrically, they are nonpolar and draw only 5.4 W per bulb. Output is spread omnidirectionally across 270 degrees.
Options
- Amber: for amber turn signal lenses, typically the front signals.
- Red: for red rear signal lenses.
- Single or Pair: buy a single to replace one bulb, or a pair to do both sides at once.

Will it fit my truck?
It replaces 3156/3157-size turn signal bulbs; see the fitment list for the Chevy, GMC, Dodge/Ram, Ford, Jeep, Lexus, Nissan and Toyota years. Call or text the real humans at NVMOS, (920) 249-7744.
XP80 or HP11?
XP80 puts out 510 lumens per bulb versus 310 for the HP11, so it is the brighter option.
Amber or red?
