Why Tail Lights Stay On When Car Off

It’s that time of year again when you get a call from your insurance company, asking you to come in for a free inspection. This time, they’re not looking for any problems – they just want to see if you’ve been driving with your tail lights on. And if you have, there’s now a good chance you’re going to be getting a ticket.

What Causes Tail Lights to Stay On When the Car is Off?

Tail lights stay on when the car is off for a few reasons. The most common reason is that the low voltage wire that runs from the battery to the tail light is still energized. This wire will keep the light on even if the car is turned off. Occasionally, another wire in the system will become disconnected, causing the tail light to stay on.

How to Fix a Tail Light that Stays On When the Car is Off

If you find that your car’s tail light stays on even when the car is off, there may be a way to fix it. Tail lights are usually turned off when the car is in park or in neutral, but due to a faulty switch, your tail light may stay on. To fix this, you’ll need to replace the switch.


It can be really confusing when your car turns off and the headlights stay on. After all, you’re supposed to turn them off so that you don’t waste energy! But what’s going on?
