What does this light mean? pic inside

[Supra2NR]

i wouldnt worry about it, toyota made that to warn owners when thier taillight blows, that was a great idea except , i dont think you can reset that sensor, i've been looking for ways to do that ever since i got my car

im jus gonna change the blulb blue since its always on , so at least it will look
nice on my dash

this is the first car that i drove that had this, this is the only car that i know that have this,, people have got by for decades without knowing that their tailights are out, you'll jus get a honk from other drivers that passes you telling you to replace it

good luck hopefully u wont get rear-ended if your lights go out
best of luck to you bro, knock on wood
