I was in heavy traffic and almost was rear ended because my brake lights went out. I back up into my driveway every day. So I've seen the reflection of the lights on my fence. I didn't know they would go out while I was driving! This could get someone killed! The person behind me was nice enough to let me know my brake lights were not coming on when I pressed on the brakes. He said the top light comes on but not the ones on the sides!
