Re: Which wire is the low beam wire for a 2002 hyundai...
I would install the fog lights off of ignition battery, (power when key is on), connecting thru the headlights could put too much current draw on the headlight circuit.

one wire will for high beam
one wire will be for low beam
the last wire will be ground wire
as fog light have only one beam you can use the low beam wire and parallel wire it to the fog lights
that way you have the head lights still and the fog lights as accessories correctly wired according to regulations
how to do it simply-- find the low beam power wire ( light switch on low beam and power at the light bulb check ed with a multi meter set on volts
solder , piggy back, or double plug in a connection into that wire and run one wire to the left fog light and one to the right fog light connect each fog light to an individual ground wire and connect those wires back to the ground wire for the main lights
Now having done that simple addition to the lighting system another problem has come up
The wiring will now be too light to carry fog light current and or the light switch will burn out
To over come this problem, the circuit needs a relay
fit a relay on the bike and now run the low beam wire to a terminal of the relay
run the other terminal wire to ground
this enables the relay to operate when the low beam is switched on but at this will not switch on the lights yet
now you have to run a heavy gauge wire (fused at the battery) to one of the power terminals of the relay and from the other power terminal to the connection for the fog and low beam lights
Now it all works switch on the high beam and no for lights
change to low beam and the fog lights come on as well
All nice and legal
Of course if you don't care about being legal just buy a 30 amp toggle switch and run a fused wire directly to the switch from the battery to the lights and then to ground from the lights
You will know that the generator / alternator for the bike will not be able to run the fog lights with or without the main lights so what will you have achieved
sometimes they are connected with the low beam headlights. when you turn your low beam on, the fog lights would come on too. if they are factory installed.
if you are just going to install it, you can put a separate switch if you want to.
Your fogs only working when low beams are on is normal, as far as your low beam lights not working, I would have the headlight switch checked, or check for a bad fuse or possibly a relay if your car has a light relay. Some do and some don't, I am not that familiar with your model of car to tell you for sure.
Hi ,Check the light bulb,see if its seat in the seats properly 'for earth' and the light terminals for dirts ,grease,or corrosion.clean if needs to.I think its a Earth problems
It sounds like a blown fuse. Are you checking them with a test light? And have you located all of the fuses. there will typically be a fuse box under the drivers dash area, and one under the hood. have another look Im certain you'll find a blown fuse. Good luck.
Check for headlight relay and fuse. Some cars have separate circuits for head light flasher and normal high/low beam. From your description, I would suspect a bad connection to/from relay or relay itself.
