What are the reasons for a motorcycle's brake light not working?

The reason for a motorcycle's brake light not working is usually a burnt-out bulb, which can be fixed by replacing it with a new one. The brake light is typically installed at the rear of the vehicle and features a red-colored main body to enhance light penetration. This ensures that following vehicles can easily detect when the motorcycle is braking, even in low visibility conditions, thereby helping to prevent rear-end collisions. Motorcycles are gasoline-powered vehicles with two or three wheels, steered by handlebars for front-wheel control. They are lightweight, agile, and fast, widely used for patrolling, passenger and cargo transportation, and also as sports equipment. Broadly speaking, motorcycles can be categorized into street bikes, road racing motorcycles, off-road motorcycles, cruisers, and touring bikes, among others.
I've fixed quite a few motorcycle brake light issues and found several common causes. First is burnt-out bulbs, especially those old-fashioned tungsten filament bulbs that can easily blow - just a few bumps on rough roads can snap the filament. Second is wiring problems; if the harness between the brake light switch and bulb gets chewed by rodents or the connectors corrode, current can't pass through. Then there's the brake switch itself - when you pull the brake lever, there's a small spring contact inside that can get stuck or develop poor connections over time. Blown fuses are also quite common, particularly on bikes modified with LED lights that may have unstable current. Brake lights are life-savers - last time a rider got rear-ended because his light wasn't working, which was really dangerous. I'd suggest checking the cheapest components first (bulbs and fuses), and if that doesn't work, have a professional mechanic check the wiring rather than messing with circuit boards yourself.
