my experience with LED... they DO NOT illuminate down the road, yes they are bright, but do not cast a beam of light farther down the road than halogen light do, I have 4 or 5 different led bulbs ,( some rated 300w!) that I;ve tried in my GMC pickup, only to go back to halogen. where I live, seeing as far as you can down the road is critical , as we have range cattle roaming the roads, and at night, can discolor your underware real fast!
