Have you upgraded any lights to LEDs? This answer can apply to any car with this problem but only if LED lights are used.
This can be caused by LED 1157 tail/brake combo lights. The problem is that the tail and brake lights are not always as isolated as they should be.
When the brake lights are powered on the tail light terminal becomes live. This voltage will power up the park light circuit ie. tail lights, front park lights and instrument panel.
The "short" comes after the LED resistors in the 1157 therefore the leaked current is low and will not usually cause any problems unless you have LED's throughout the park light circuit, there is insufficient current to turn on standard light bulbs.
Solution is a diode fitted in line on the tail light wires to the 1157s allowing current into the 1157 but not out.
check the brake pedal, there is a switch on the back of the pedal that depressed when the brake is depressed that turns the lights on, when this is loose it keeps the lights on.
Brake lights are on continuously while you are driving. Every time the brake pedal is depressed.
Check the ground wire to the brake lights.
yes, they do
Possibly the brake light switch at the brake pedal has stayed depressed or stuck.
The fuse for the brake light on a Hyundai Accent are found in the engine compartment. The fuse is number four in the fuse box, and is rated on 10 amps.
Check the brake switch under your pedal (which needs to be pushed when the brake pedal is depressed). This is what the problem was on my friends Sentra. As long as you have checked the lights and fuses, this should do it.
Check rear bulbs, rear brake bulb fuse, and check the swith on the brake pedal.
It is because the brake light switch under the brake pedal is faulty. usually replacing this will solve the problem. it is designed in such a way that when the brake pedal is depressed the switch completes a circuit and the lights come on. the fault occurs when the switch closes the circuit even though the pedal is not depressed. hope this helps.
Check for a bad ground circuit at the rear tial lights.
It turns the rear brake lights on as a safety feature. The brake pedal is pushed in, causing the fluid to move forward in the brake cylinder,activating a brake light switch. Even if the vehicle is off, the lights will still come on.
The tail lights and the stop lights work off of different circuits. The stop lights work when the brake pedal is depressed while the tail lights work when the light switch is turned on. Look for a burnt fuse or a bad connection.
