For brake lights in particular, there is one huge advantage going to LED.
Incandescent bulbs light up approximately 0.5 sec after power is applied.

That means the driver behind you gets an extra 0.45 sec to react. May not sound like a lot but even if they still hit you, it will be at a slower speed and therefore should be less serious.
True it's a bit off topic, but you can break it down even further.
At 60mph your car is traveling 88 feet per second. 5260/60=88
At 88 feet per second you are traveling 8.8 feet every tenth of a second. 88/10=8.8ft
Now take the numbers from valhalla360. Even rounding the .45 down to .40 you will travel 35.2 feet in 4 tents of a second. 8.8*.4=35.2 That's more than the length of a standard traffic intersection. So the LED coming on .40 seconds faster than the incandescent will give you an additional 35.2 feet of stopping distance.
