I would presume you have H7 fitting and you have swapped the bulb with a known worker as a 1st check, then go for a fuse check, and then a plug in relay.

While the bonnet is up and you're checking your connector also move any wiring pertaining to your lights in case there is damage, also check the earth.

If you have a meter don't rely on a 12v reading it might be high resistance and not enough current is flowing.
Best way is to use a 12v 21W and a length of wire.

I did not find any fuse on my fuse chart for the the low beams, I do have a good bulb I bought a new one
