Acura RL headlights and taillights remain on when vehicle is powered off on Acura RL

Some Acura RL owners report experiencing issues with their headlights and taillights remaining on even after the vehicle is powered off. This problem may stem from a small plastic pad or plug that fits into the pedal, which is intended to activate the brake light switch. Additionally, if the taillights stay illuminated despite using the on-off switch, it could indicate a fused shut power switch or a wiring fault keeping the circuit powered. For headlights that remain on, potential causes include a faulty relay, a malfunctioning timer, water ingress, faulty sensors, or issues with the daytime running lights. Moreover, some owners report their headlights cycling on and off, which may be linked to problems with bulbs, fuses, the headlight relay, or the switch itself. It is advisable for owners experiencing these issues to troubleshoot the electrical system and consult a professional mechanic or authorized Acura service center if the problem persists.
