High beams are the bright headlights on a vehicle that provide increased visibility at night or in low-light conditions. They illuminate a larger area ahead, allowing drivers to see further down the road. High beams are typically used when there are no other vehicles nearby, as they can be blinding to oncoming drivers. When using high beams, it's important to switch to low beams when approaching other vehicles or when driving in well-lit areas. This helps ensure safety for all road users. Most vehicles have a simple switch or lever to toggle between high beams and low beams.
