Everything DakotaDude said about the high beam HID lights is true,
but I'm of the opinion that the high beam is worth adding,
whereas the low beam is a "must have".
the HID low beam is so bright that the stock high beam becomes pretty much useless
if you do ride rural occasionally the HID high beam is amazing,
it's true you can't "flash" an HID, flip the switch and you can actually watch it slowly get brighter as it warms up.
now here's the good part,
once "she" warms up and lets say you dim your brights for an oncoming vehicle
when you go back to high beam within a couple of minutes (as long as it's still warm)
it's as bright as it was before you dimmed,
riding in deer country HID high beam is very useful.
And I promise you will not have any trouble "convincing" oncoming traffic to "dim their brights"
