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

The Diode Dynamics H13 SL2 LED Bulbs are a direct plug-and-play replacement for H13 bulbs, sold as a pair. They are fanless, use automotive-grade multi-die LEDs and keep the driver inside the bulb, so the package stays compact. This version is cool white (6000K).
Why it works
No fan means one less moving part to wear out, and the integrated driver means there is no separate box to zip-tie somewhere behind the headlight. The body is die-cast A360 aluminum over a copper PCB, cooled passively by the heatsink. The driver is constant current with transient protection, and the bulbs run on 9-30V. They have passed the SAE J575 durability test, and they are designed and engineered in the USA (patents pending).
Fitment
Diode Dynamics lists this bulb size for:
- Ford F-150 2004-2014
- Ford Super Duty 2005-2022
- Jeep Gladiator 2020-2021
- Jeep Wrangler 2007-2021
- Ram 1500 2006-2012
- Ram 2500/3500 2006-2010
The same truck can use different bulb sizes for low beam, high beam and fog depending on trim, so check your owner's manual or the bulb you are pulling before you order.

Diode Dynamics H13 SL2 LED Bulbs (Pair) FAQs
Is this a pair?
Yes, two bulbs.
Do I need an external driver or adapter?
No. The driver is built into the bulb and it uses an OEM-size plug-and-play connector.
Does it have a fan?
No. The SL2 is fanless and cooled passively by its heatsink.
Will it fit my truck?
Check the fitment list and your owner's manual for the bulb size in that position. Call or text the real humans at NVMOS, (920) 249-7744, if you want a second set of eyes.
