LED's?

Now i heard that with LEDs they only shine directly outward instead of incandescent lamps that shine in all directions. This is important because the light reflects off the inner housing of the tail lamps and turn lamps whereas a led doesn’t do that. That would make a lamp that is not as bright.. right?

yes but the bulbs wernt as bright, thes leds shine directly on the lens and make it twice as bright from the front and i stood at an angle from the light and it stilll looked just as bright
