Frequently asked questions

What is the operating voltage of the g-Brake Lights platform?

The system is designed to operate from a 12 V battery, though it can be modified for lower voltages.

How many brightness levels are available based on deceleration?

The platform supports more than 1,000 programmable levels of brightness determined by vehicle decelerations.

What is the maximum high shock survivability rating for the accelerometer?

The low-g accelerometer offers high shock survivability up to 10,000 g for a duration of 0.1 ms.
