How does this third brake light improve rear visibility and safety?

The PIT66 LED brake lamp emits quicker, brighter light than many incandescent units, making it easier for following drivers to notice braking events. While not a substitute for safe driving practices, the faster illumination can help increase rear noticeability in traffic.

• LED technology provides faster on-time compared to traditional bulbs.

• Clear lens and focused LED array improve recognition in daylight and at night.
