Problems with Hazard Lights directly after start

Hey People,

i do have a Problem with my EU-Prius 3. Since a while it happens, every then and now, that the Hazard Lights went on and stay on. First I thought it might be the LED Lights from China, that I have installed a while ago. But Nothing. Then i thought a Problem with the 12V for car charger in the middle next to the seat heater - but Nothing at all. It happens, that they just go on when you get into the car, after a while, you can push the button for the Hazard Lights and they went out. On other days it happens, that they wont get off. Then you park the car and the next day, they are off. Also sometimes it happens that it stays on after shutting off the car.
Does anyone have an idea or even a clue what it could be? My idea is, for now, that it is the button of the Hazard Lights.

Hope, someone might have a clue

So far

Sincerely, Dominik

 

ok thanks.
