LED vs Standard bulbs

Had a discussion about these with an Electrical Engineer at work, he wanted them for his 72 C-10. He pointed out that the stye of LED you posted pics of transmit light in one direction and a bulb transmits light spherically, counting on the reflector and lens to aid in light piping. So you either need an LED "bulb" that transmits light like a traditional bulb or a lens housing designed for LED's. If you look at current OEM LED tail lights etc, you'll see they did the latter of the two. Just like Bi-Xenon or HID headlights, the optics are just as important as the bulb and ballast for it to work as intended.
