Headlights turning completely off when switching beams
Switching between high and low beams can cause the headlights to shut off completely or stop working altogether, requiring drivers to repeatedly flip the switch or hit the dashboard to get them back on. This dangerous failure leaves drivers temporarily blinded in the dark and unable to rely on their main lighting while driving.
