if you buy the lights from the auction, they should work nicely. As Strife said, they are virtually "instant on" (like milliseconds) versus standard incandescent. At speed, that can buy a significant amount of distance to help prevent an accident. This is the exact reason why highline automakers are moving to LED brake lights.

If you buy the "over-the-counter, pop-in lights" from pepboys, then you will NOT have enough light.

I am going to build something like what you see using the OEM lights, but I will also include the taillights, rear fog, rear side marker, along with the brake lights. As of yet, effective white LEDs are not practical for reverse function….even if using Luxeon Star’s or IO Moons. They run too hot, need heat sinks, and don’t have the ability to project light like standard bulbs do…..at least not yet.
