One Light To Rule: Considering how good the SS3 LED Kit from Diode Dynamics is, it's tough to argue that there's a much better product on the market in terms of performance per dollar for your Sierra. It uses proprietary Total Internal Reflection (TIR) technology to channel every bit of the LED Light source onto the target. That may not sound like much but consider this. Most rivals lose up to 10% of their output to internal surfaces and glare. That means that the SS3 ends up with more usable light on your target. It also comes with everything you'll need to get the job done right with brackets and wiring ready to go.

Driving or Fog: The SS3 is available in SAE Driving or Fog Light patterns. Both are exceptionally good at accomplishing the task at hand with a base lumen output of 1,300 and ramping up to a mighty 3,000 depending on your personal configuration.

Make It Yours: Speaking of configuration, the SS3 can be had in many flavors. Aside from choosing driving or fog patterns, you can also pick from the Sport model or double the power by going with the Pro version. Add to that yellow or white lenses and you really can tailor the SS3 to your personal preference.

Confidence: Diode Dynamics has real belief in their products and they back that up with an unprecedented 8 year warranty on this product.
