If it's a factory type LED then there's no discrete low beam bulb and the low beam isn't serviceable. Nobody I know about makes aftermarket clones for the Nissan setup, so if you can't find a bulb to replace, it means it's almost certainly a Nissan OE assembly. The accident may have tilted the circuit board or damaged the reflector, but there's no way to verify that without cutting the unit open. So you're probably SOL short of replacing the assembly, and get your wallet ready for a whack if that's the case.

Yep, that will definitely do it. The genuine LED headlight assemblies list for about $1500, so body shops definitely try to dodge on them when they think they can get away with it.
