Baja Designs has been a leader in the off-road lighting industry for over 25 years. Today’s aftermarket is dominated by forward project LED light bars, which was initially developed by Baja Designs and used in the 2005 Baja 1000. They specialize in LED light bars, LED auxiliary lights, laser light bars, ATV and UTV lighting, and more. They refer to their team of engineering as “The Scientists of Lighting” thanks to their ability to push the industry forward and create new products. One of their latest innovations includes laser lights, offering unparalleled lighting distance compared to any other LED light bar on the market. Their products are 100% designed to be brighter, bolder, and better than any other lighting solution available.
Why Choose Baja Designs?There are tons of different lighting companies on the market, why should you choose Baja Designs? There are a few reasons why you should choose a Baja Designs light bar, but they all relate to build quality, performance, and design.
Build QualityWhat good is an off-road light if it can’t withstand the abuse of off-roading? Baja Designs lights are the toughest on the market, with an IP69k water/dust proof rating and MIL-STD-810G compliance. Baja Designs developed technology like their MoistureBlock power cord, which further improves water proofing even if you cut the plug off the end of the cord! Even if you can somehow break your Baja Designs light, they’ll back it up with their lifetime warranty.
PerformancePerformance is one of the key factors when deciding what LED light bar you want to buy. Thanks to the insane amount of research and development on Baja Designs’ part, they’re able to offer the brightest lights on the market. They specifically use 5000k LEDs and invited technology such as CopperDrive which allows them to drive their LEDs at 100% without overheating. Further improving their performance is Baja Designs’ proprietary ClearView optics.
DesignOnce you add in lights, a sound system, and other accessories on your vehicle, your charging system may have a hard time keeping up with the demand. For this reason, Baja Designs created their new Battery Management Tech which allows the light bar to throttle its output if it detects a drop in below 13.5V in your vehicle's charging system. Baja Designs specifically uses replaceable lenses and optics to make it easy to fix your LED light bar if the need arises.
The Purpose of Amber Lighting
When you’re out ripping around the desert, it can quickly become difficult to see if you’re following someone else or the conditions are dusty. The problem with standard LED light bars, is the light will just reflect off the dust particles and end up making it harder to see. This effect can be especially frustrating if you’re racing, as you’ll be driving blind. The purpose of an LED light bar is to cut through the dust and illuminate the trail. Amber light cuts through dust, snow, and fog better than white light because of orange light reflects off those objects compared to white light. The easier it is to see in low visibility conditions, the faster and safer you can drive!
Understanding Lighting PatternsAs you may have figured out by now, there are tons of different lighting patterns associated with LED light bars. The two most common beam patterns include flood and spot. Each beam pattern has a specific use, and neither one is better for general use. To put it simply, flood lights use a very side and broad beam pattern. This allows more of the trail or road to be lit up in front of you, but the light won’t travel far. Spot beam light bars are much tighter and won’t illuminate the entire trail, but the light is projected much further, allowing you to see much farther down the trail. For general trail riding, either one will work fine. If you plan on pre-running or racing, then a spot beam light bar will be a much better option. If you end up driving faster than you can see, it won’t be long until a bad situation arises. For those who need to see as far as possible, Baja Designs developed their Laser lights which offer unmatched lighting distance.
