Actually all I was saying was the bright elements of the 1157 bulbs were 
working with the brake lights and the dimmer elements work with the tail 
lights. I assume this is the way they are supposed? If not they have 
been this way every since I can remember. I will posted a video of the 
light function and just let everyone be the judge. Sorry for any 
confusion.
