had 1987 Dodge Aries with same thing wrong, its was bad ground wire just ran new ground wire from rear harness to a screw I put in rear metal tail panel it worked.
The light switch.
If the headlight that runs through the modulator first is out then the daytime running lights won't work. Change the bulb and the daytime lights should then work.
Check the bulbs to see if they are shot. If that does not resolve the problem check the fuse. If that does not resolve the problem take it to a mechanical and have it checked for wiring problems.
Have your alternator checked out.
to wire the license plate lights you must have lights and wire them to the scooter.
No, the license plate light is wired in with the rear tail lights, not the brake lights.
The license plate lights are not in a separate fuce by it seft. They are the same as your side marker lights. So, check if your side marker lights are working and if they are them is a bad license plate light bulb.
Brake lights and tail lights. (Unless you have a spotter telling you of course)
That would be the lights that illuminate the rear license plate.
Tail lights. Brake lights. Backup lights. Signal lights. License plate lights.
Check your fuses
yes 2002 Ford Focus do have 2 lights on license plate
