Evolutionary: The all-new XB Evo LED Fog lights are the latest iteration of a hugely successful product line launched over a decade ago that has been upgraded in every way. Now fitted with the latest in technology, compliance, quality, and styling, these fog lights are designed for enthusiasts who are serious about all the above. They are the perfect addition to a set of high-performance headlights, ultimately maximizing your visibility when the weather conditions call for help. Maximum Performance: Thanks to an array of Osram Oslon-PL LED chips paired with an advanced optic, all designed in house by Morimoto's lead optical engineer Yoshi Ishida, the XB Evo fog lights will meet & exceed the highest expectations in the performance department. They offer the industry's best combination of beam width and intensity, and are fully compliant with the latest SAE J583 F3 and ECE R19 regulations for on-road use in North America and EU. XB, Evo, and Evo+: While the standard XB LED fog is a massive upgrade over stock halogen fog lights, the new XB Evo models take performance to the next level. Their recipe delivers more of everything one would ask for in a good fog light and is available in two distinct versions: a dedicated, white-output model, and the XB Evo+ which can be switched on-the-fly between white and yellow. Unique to the XB Evo+ fog lights is the zero-compromise distribution of light within the beam regardless of which output color is selected... which cannot be said for other switchable fog lights on the market. Competitive Advantage: The XB Evo fogs don't have back lights--and they aren't as "bright" as some of the competition either... but for those who want nothing more than an all-out performer for the street, the XB Evo will still win in the real world. Why? It's the only dual-color fog light on the market that is SAE compliant in both colors. The beam pattern offers superior coverage off to the sides of the road with a generous 90 degrees of width, which is considerably more than most fogs out there which only cover up to 80 degrees. And the intensity? Yes, some other fog lights are slightly brighter, because they sacrifice coverage for candela---which doesn't actually make sense from a practical standpoint. A fog light that out-shines your low-beam only compromises your ability to see into the distance. This is because the retinas in our eyes auto-adjust to the extra light in our nearfield. When it comes to fog lights, there is such a thing as too bright, but there's no such thing as too wide, and the XB Evo strikes the best balance here. OE Fit & Installation: The Morimoto fog lights are expertly crafted to match all OE specifications to ensure perfect fitment and hassle-free install. They're designed as a direct replacement for the factory fog lights. The wiring is plug and play with the factory wire harness. Their integrated aiming adjusters allow you to dial in the beam height as well. Thoughtfully engineered for a modification-free install. No factory warranties void. No headaches. Well-Built: This product is completely designed, engineered & tested by the Morimoto team to meet the high expectations of our customers. High quality OE-grade LEDs used throughout. All wiring and connections are OE-grade. When it comes to UV protection, Toyota has best in class protection. That's why we've formulated a new hard coating that meets and exceeds Toyota's standard for resistance against cracking, fading, and yellowing lenses from UV exposure. The list goes on but as the saying goes: you get what you pay for. Morimoto fog lights aren't the most affordable, but they are built to a high standard and should easily last the life of your vehicle! We're proud to stand behind the product with an industry-leading ten-year warranty. If something fails prematurely, we have you covered!
