mine are actually decently bright, will i want them to light my way durning the night though, not really. just dont try to do more than one light per connection and you should be fine. The tan wire will go to the red wire on the light, and that black wire will go to your other black wire on the light. if the lights you are putting on are black and white wires, put black to black, and tan to white. It really doesn't matter because you are still making a circuit through the bulb, but it helps to understand what you have done later on throughout your mod processes.
