Not much of a description.
Must have been a heckufa bump.

I've never heard of any red and white alternating circles. Where are they? Pictures really are worth a thousand words.
I'll take an ignorant guess and offer blind spot warning as one idea. That can happen if you hit a bump so hard that it knocked a sensor loose.
Could be a parking brake issue. It all depends on where these circles are and what they look like.
Chances are, you'll need to see the dealer.
