My car is new, 2013. I have two very bright led tail lights for braking, and an **aftermarket** third middle brake light in the window. 

**I am in Texas**

I'm trying to wrap my head around how bright the middle tail light needs to be. I have read [this document]( many times.

Here is what I know so far.

1. Figure 1a, 1b, and 1c are the meat and potatoes. They state minimum lumen for stop as 80-300. 

2. Figure 1c states the sum of percentages of the lights, meaning if they are higher than 65 lumen not all lights need to meet the minimum of 80 lumen (? yes no ?) 

3. S.5.1.1.6 means that as long as the average of lights are brighter than the minimum requirements, not all lights need to meet the minimum lumen of 1b? 

Basically,

What is the minimum lumen of the 3 brake lights in my car?

I have two brake lights that are north of 200 lumen, and a third middle brake light that is only 57 lumen. I'm trying to verify if the middle brake light is legal since the average of all my brake lights is higher than the minimum required by figure 1c. And S.5.1.1.6 states that if the average is higher than the minimum average, not all lights need to meet the minimum
