Product Features
1. When you step on the brake pedal, the brake light and tail light of the car will light up at the same time. Release the brake pedal and the brake and running lights go out.

2. When you turn on the car tail light, the brightness will drop to 30% of the original. When you press the brake pedal, the taillight brightness returns to 100% of the original car. This design makes it easy for you to brake at night, and the taillights and brake lights work at the same time, instantly increasing the brightness and allowing the vehicles behind to see your brakes more clearly.

Question 1: Why is the brightness dimmed when the car taillights are turned on after installing this product?

Answer: When you drive at night, for safe driving, you will turn on the rear lights of your car. When you press the brake pedal, the tail light and brake light come on at the same time. But due to night driving, the taillights are always on, so it will look like only the brake lights are on. So the design of the product is to reduce the brightness of the taillights to 30% when the brakes are not applied, so whether it is day or night. It can achieve the visual effect of brightening brake lights and tail lights at the same time

Question 2: Why can't the car lights become brighter after installing this product

Answer: Because our product is just a brake light wire set, not a brake light. The brightness of a car light is determined by its own LED brightness. We can only dim it, we cannot further increase the maximum brightness of the car light
