![]() This technology is relatively new to Baja Designs, as we traditionally control our off-road light patterns through a reflector and our Clearview optics for a vertical and horizontal spread. Projector Optic TechnologyThe Baja Designs S2 SAE incorporates technology from the all-new Next-generation Squadron SAE, utilizing aspheric projector optics for a controlled sharp cutoff that keeps the light beam pattern low and out of the eyes of oncoming traffic. The S2 SAE brings the highest level of road-legal performance for your vehicle in a compact size, no matter the conditions. Utilizing advanced LED technology and aspheric projector optics, the S2 SAE provides controlled, sharp cutoffs for optimal visibility on the road while meeting SAE J583 fog requirements while being available in either clear or amber. ![]() PowerThe Baja Designs S2 SAE delivers an impressive 1,210 lumens per light at a power consumption of only 12.42W. The S2 SAE will be sold as a pair starting at $289.95 with universal mounting hardware and standard wiring harness. The S2 SAE takes this versatility even further, with its SAE-compliant design allowing it to fit virtually anywhere on a vehicle. It can be used for driving, fog, cargo, and even chase lights. Size and VersatilityThe Baja Designs S2 set the stage for a compact light at only 2.93" big, the S2 is one of the most versatile lights in our lineup. Highly controlled light pattern with sharp cutoffs Plug-and-play solutions for many OEM fog lights Achieving exceptionalism has been our journey ever since, and now we strive to set a new standard in performance lighting yet again with the Baja Designs S2 SAE, the next evolution of our SAE road-legal fog light lineup. The Thule Aeroblade and Rhino-Rack Vortex bars both feature noise reducing strips that makes them almost silent in many applications.When Baja Designs launched the S2 in 2012, we set the standard for a compact performance off-road LED light. The new aero foil cross bars provides a significant improvement in roof rack noise. And it's a fraction of the price of a new profiled bar. This does an amazing job of bringing down the noise. If you want to go low-tech, try wrapping some bungee cord in a spiral around your cross bars. In many cases the padding also reduce side to side movement. An added benefit is that the pads serve as protection when strapping surfboards, SUPs or any other flat piece of gear to your roof. ![]() Wrapping the cross bars in pads also disturbs the airflow over and around the bars thereby reducing the humming or whistling noise from a naked roof rack cross bar. This helps reduce windnoise significantly.īut what about a square or round bar? We recommend using padded cross bar pads. Most of the premium racks comes with some type of textured rubber insert that disturbs the airflow and breaks up the frequency of the Aeolian noise we mentioned earlier. Using a wind fairingwill definetely help in reducing wind noise, but let's face it, it's just another piece of flimsy kit that gets in the way of loading and unloading your gear. A wind fairing is a plastic shield attaches to the front cross bar and attempts to divert airflow over and away from the bar to reduce wind noise and drag. Most manufacturers have one in their product line-up. The first option is to add a wind fairing. The secret to reducing the noise from a roof rack is by either diverting or disturbing the airflow around the cross bar. A square bar has a drag coefficient of about 1.05 a sphere is around 0.47 and an airfoil is as little as 0.04. If you compare the different shapes of cross bars, there is a masive difference in the drag coefficient between them. ![]() The higher the drag coefficient, the more noise is created. The amount of noise depends on the speed of the airflow (how fast you are driving) and the drag coefficient of the cross bar. If the surface the wind passes over has a consistent shape, the disturbance becomes tonal and at certain frequencies very annoying. The wind noise we hear from some roof racks is known as Aeolian no ise and is produced by wind when it passes over or through objects.
