Activates on Hard Braking

Since it only activates when you’re likely to be rear-ended, it’s never annoying and has maximum impact when you need it.

Extremely Attention-Getting

Impulse is 3 times as bright as your normal brake lights and pulses quickly. It’s impossible to miss.

Distracted Drivers React

Because Impulse is so bright, it even gets the attention of a driver who’s looking down at their phone.

4-Year Battery Life

Impulse never needs charging, yet it reacts faster than the blink of an eye. Literally.
