they actualy arent very expensive at all. ive had them on my truck for 2 years. Not the blue ones though, i hate those. mine are very white. however, they are not high draw at all, in fact they have less draw than a halogen bulb. Also they are not very failure-prone. in the 2 years i have had them, only one of them went out and it was because of moisture in my headlight. same thing would have happened with a regular bulb. it will be several years before they are replaced with LEDs.
