Yaris 2010 original LED tail lights

[Risto]

Hi, I have 2010 XP90 yaris and wife is now running without tail lights. It has LED (original) tail lights. Same led acts as running light and brake light. In brake there is 12V and in normal case probably something else? My problem is that without braking there is no voltage to led. Leds are ok but issue is with voltage. I have checked tail fuse and tried to understand relays as well. Probably there is no T-LP relay at all. Also tried to clean and understand light control switch. Still no idea how voltage is generated to LED in normal case (without brake). Is it 6V or something... Do you now if there is some voltage regulator to drop voltage or how it works? Or is it ECU which drives correct voltage to LED? All other lights are fine.

Thank you!

You should forget that question. I did stupid mistake. I was sure that tail leds are not only for breaks. But they are. Only parking lights are on with head lights...
