I was just wondering if any of you experienced your third brake lights (in the rear spoiler) getting dimmer. Mine still works, but don't glow like they used to. Help!

 

Replace the bulb. Old bulbs become dimmer from long use. Clean the inside of the housing and lens.

 

On my car a SE the 3rd brake light stopped working all together,it had shorted out due to water getting in there.You could see the water some that maybe what's happening to you

 

The strip of lights in the spoiler is one bulb? I thought LED' just stop working when they burn out. So is something not getting enough current? Or are the LED's getting old like you said?
Thanks,
Shiggy...

 

I was wrong. The post was clear but I misread it as the no-spoiler, inside-the-car Center High Mounted Stop Light.

 

Most people report it easier to replace the entire rack of LEDs than try to fix individual LEDs.
