I don't know what kind of car you have, but if the headlights work in either the dim or bright mode, but not both, I would suspect the dimmer switch. If they don't work at all, the headlight switch is probably the culpret, unless of course both bulbs are burned out, which I have seen on one occassion.

How do you change a starter or an ignition switch in a 1998 Mitsubishi Montero?

Forget the ignition switch for now it is most likely not your problem. I assume a no-start.First have assistant turn on headlamps while you observe from front of car. As you observe, have them try to start car. Did the headlamps light? Did they glow less as the car was cranked? No headlamps or dim headlamps whilw cranking indicate a battery, battery connection, battery cables. Clean or replace these. If headlamps were bright then we can look at the starter. Raise vehicle safely, block rear wheels, put in park. Go under car and take a screwdriver and short across the starter terminals. A bad starter will only spark. If we determine starter is bad, remove the negative battery cable. Under car, observe the size of wrenches needed and then remove the 2 or 3 wires on starter, 2 or 3 starter bolts and any brackets that are in the way. Once unbolted, the starter will be easy to remove. Take it to a auto store that tests these free ,just to reconfirm it is bad. Reverse the procedure.

The battery symbol lights up on your dashboard car wont start Battery seems ok Replace alternator?

Do the headlamps work while cranking the starter? If not focus on your battery and cables. Jump start the car and have the system tested before you throw more dollar bills at this problem; it could be the alternator but have it tested first.

If you do not have low-beam headlights always drive with what?

All vehicles are required to have low- and high-beam headlamps. If your low-beam headlamps both fail after dark, try switching to high beam. If the high beams don't work either, switch on the emergency flashers. In either case, get the car out of traffic and off the road as quickly as safely possible.

Why don't they work 1986 Honda accord lx headlamps don't come on you replaced the fuse and headlamps but still don't come on other lights work though?

Look at the wiring bundle that feeds the headlights. The wires will eventually break because of the constant up & down flexing of the wire bundle (motorized hidden headlamps). The problem will likely be found within inches of where the bundle is secured to the inside of the popup headlight carrier (where the flexing would be concentrated).
