Headlights stopped working after only 1 year… Why?

someone reversed into my car (2014 ford focus ST) about 1 year ago when my brother owned it. The car was repaired at an authorized AAA body shop, so luckily there is a lifetime warranty on any of the parts that were replaced.

Anyway, one of my headlights went out after only 10 1/2 months (got new headlights following the collision)
and the shop ordered me a new one and I got it for free. Fast forward to 5 days ago… The other headlight went out. Im getting it fixed again for free… I do not know much about cars, but I know I shouldn't have to be getting new headlights after barely a year.

Could it be something besides the actual headlights, like the wiring?

I am going to the repair shop tomorrow, should I ask them to look at anything else besides the headlights?

Thanks for any advice
