Why does the reverse light stay on when driving Citroen C3?

If the reverse light on a Citroën C3 stays on while driving, it may be due to a malfunctioning reverse light switch, which is typically located on the transmission. This switch may be stuck in the "on" position or have a wiring issue. Additionally, a short circuit in the electrical system could cause the reverse lights to remain illuminated. It's advisable to have the vehicle inspected by a mechanic to diagnose and resolve the issue.
