Or you have quite bit of resistance "upstream" from the tail light fixtures. That resistance translates in to voltage drop. The easy way to test that is just run a ten foot piece of lamp cord from the positive side of your battery to one of the fixture's wires (first brake/signal then tail), and run the other leg of the lamp cord to the negative side of the battery and to the ground of your light fixture. If the LED lights up nicely doing it that way then you have voltage loss through that circuit when it's trying to operate normally. It could either be on the positive or ground side of the fixture. My feeling is if that battery has enough juice to start your car then it has a enough juice to light your LEDs.
