3. Installation of the light bar takes about two minutes, but we highly suggest getting a friend to help hold it in place while you tighten the bolts on. At more than $700 for a 20-inch Stealth Bar (size of bar tested), it's not something you'd want to drop during installation. That being said, the Stealth bar and all its LEDs would likely survive and still function properly if dropped, as it's very durable. It'd just be terrible to have scratches on a brand new bar.
