So I've changed my 3rd break light twice in 6 months. It keeps going out fast. I've checked the bulb is have in now and it looks good. But doesn't light up. Smh. The warning light is passing me off. I thought it could be because I have a 10in kicker sub and loosened it. But that's not the case

 

I guess it is caused by the R121 or related connectins in the “Multiplex Rear Junction Computer” if a USDM is the same with a JDM.

You can find the detail at below.

When the sensing resistor R121 opens or connection issues are there, the light doesn't turn on.

 

Thanks for the help I will look into it
