Ok, here are some pictures.

First, the LED by itself. Note the camera's auto-aperature stuff caused it to lose detail in the light assembly. In real life, you can see details inside the reverse assembly with the LED installed. This image taken with a flash.



Now, the 50 watt halogen by itself. In this case, you can't see details inside the assembly because it is so bright and diffuse. This image taken with a flash - notice how "blue" the flash reflection appears in the black paint, but in the LED shot, the flash's reflection just looks white. That is the camera's color-balance kicking in, just remember that the Halogen is really as much more yellow than it appears as the light of the flash appears blue.



Now both at once to get an idea of the relative strength and color temp differences. Not flash used.



Now, to see the difference between the stock 26watt turn signal and the 1watt Luxeon LED used as a turn signal, click on this link to see a short movie

Note how they appear to be out of sync because of the instantaneous off/on/off cycle from the LED.
