Coverage by product
| Product or component | Coverage |

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 3157-size LEDs for the front turn signals on 2007-2013 GMC Sierra 1500 and 2000-2014 Sierra 2500/3500 trucks. You get instant on and off, a modern LED look, and more output than the factory bulbs, with four bulb models to pick from.
Why it works
- Plug and play in the factory 3157 socket, no modification.
- LEDs snap on and off instantly instead of fading like incandescent filaments.
- Every option puts out more light than the factory bulbs.
- Diode lists the flasher setup on these trucks as a replaceable relay (EP29), which is the usual route if you want a normal blink rate with LEDs.
Options
Every kit is four 3157 bulbs. Amber options: HP48 (250 lumens) with a diffused, clean look; HP11 (310 lumens); and XP80 (510 lumens), the brightest amber here. The Switchback option is the dual-color HP24 (410 lumens) in cool white, which runs white and switches to amber for the turn signal.

Specifications
Diode Dynamics Front Turn LEDs for 2007-2013 GMC Sierra 1500 & 2000-2014 Sierra 2500/3500 (4-Pack) FAQs
How many bulbs come in the kit?
Four 3157-size bulbs in the model and color you choose.
Which bulb model should I pick?
XP80 is the brightest amber at 510 lumens. HP48 (250 lumens) has a diffusing cover for a clean look when off. HP11 sits at 310 lumens. Pick Switchback (HP24, 410 lumens) if you want a white running light that turns amber when you signal.
Will they hyperflash?
Diode lists the flasher on these trucks as a replaceable relay, EP29. Swapping to an LED-compatible flasher is the usual fix for fast blinking. Call or text the real humans at NVMOS, (920) 249-7744.
Do I have to cut or splice anything?
No. They plug into the factory 3157 sockets.
