More likely your light switch has failed.

Are the L.E.D. light bulbs the right way around in their sockets???
The ground side of the L.E.D. must go to ground!!!!!
If they are grounded the right way then all the lights will work.
Normal bulbs will work which ever way they are put in.
L.E.D. bulbs will not!!!!

if just one bulb quit working might be the bulb, connection, wiring or ground wire.
Some cars may have a fuse for different light, or multiple lights. From what I see you do not have a fuse for one low beam light.
Some cars have relays for example high beam lights I don't see a relay for one low beam light.
I think you have a bad bulb or light socket or wiring.
You can try putting the drivers side bulb in the passenger side see if it works that should tell you if it is the bulb.

Hope this helps a little. There are fuses for left and right lo beams, did you use a test light and check voltage on proper fuse. If the lo beam works on the other side, the problem isn't the relay. might be the fuse or wiring circuit? Just my opinion.
