The harder you press the vehicle brakes, the more power is sent to the trailer brakes, the harder the trailer brakes are pressed. The breakaway switch only activates the brake circuit. It is not hooked to the brake light circuit so they don't illuminate.
If the cars following you when you have your trailer break away can't tell there is a problem, the brake lights probably won't help.
Furthermore, on trailers, the brake lights are on two separate circuits and are also the turn signals. You really wouldn't want your left brake flipping on and off whenever your left turn signal is on.
