Electronics/electrical wizards-- Help settle an argument regarding LED lights

I have a chance to buy some very sturdy trailer lights. These lights were extra ones bought by a company as spares for their equipment trailers.

The systems on which these LED tail lights were used are 24V.

I want to put them on my 12 V trailer.

Person A says they will not work.

Person B says they will last longer because less voltage is going through them.

I just want to know if they will work.

Your assistance, please
