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 |

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

A four-pack of 7443-size LEDs for the front turn signals on 2014-2018 Chevrolet Silverado trucks. They plug into the factory sockets, switch on and off instantly, and put out more light than the stock bulbs.
Why it works
- Plug and play with the factory 7443 bulb size, no modification.
- Instant on and off and a modern LED look.
- Diode lists this truck as tested and confirmed with no electrical issues.
- The flasher on these trucks is BCM controlled, so if a fix were ever needed it would be resistors rather than a flasher swap.
Options
Four 7443 bulbs per kit. Amber choices are HP48 (250 lumens) with a diffusing cover, HP11 (310 lumens) and XP80 (510 lumens), the brightest of the group. Switchback is the HP24 (410 lumens) in cool white, which runs white and switches to amber when you signal.
