My last truck had HIDs in the high beam, low beam and the fog lights. With all of them on it was like a collapsed sun. They were definitely brighter than the LEDs. However there are some drawbacks. HIDs have a light off time. Having them in my high beams, meant that flashing them was not really an option since they took 1-2 seconds to warm-up. They did put off heat. A lot of heat. And if they got cooled to rapidly (water or condensation in the housing) they would burn up. Also while they were bright they had definite hot spots (so does halogen). The LEDs are more than sufficient since they are still bright (not as bright as HIDs), they run cool. Since they don't have hot spots, they light up the road more evenly and actually more usable.
