Want to install new headlights

I recently owned a 2015 Dodge Dart. I met with a small accident and headlights got damage, thank god, it did not leave scratches on the car. :uhoh:



Now I want to install new headlights. Can anyone explain how can I install it myself or should I call technical people like Utah mobile auto glass who recently replaced my old car’s windshield under insurance claim. Although I don’t want to compromise with it.
I am bit confused, Please advice!!

I NEVER HAVA A PASSION TO REPAIR MY CAR. Woman is not specialized in machanic work. I suggest, if the cost is very high, so the best way is go to insurance claim. Sorry, hope you can solve it very soon.
Good luck!

Thanks,
It was helpful really helpful, i have called the utah mobile auto glass company, they have replaced it under insurance claim, but i have been looking for a way o install it myself, but did not find anything.
