first check to make sure #1 you have the proper bulbs #2 the bulb is in the socket correctly.either of these could cause the circuit to back feed
check the fuse on the fuse box, the bulbs,or the connections.
which fuse would cause your brakelights,blinkers,dashliht not to work
A bad ground wire will cause dim headlights, or will cause lights not to work.
My '88 Prelude Si 4WS had a short in the steering column. My "guys" pulled wires to a toggle switch that they free-placed in the coin tray. It gets hot . . . But, the running lights/brake lights work independently of the headlights!
WHAT ARE YOU DUMB REPALCE YOUR LIGHT BULBS STUPID! Not stupid replaced circuit boards checked fuses ran test light . When headlights are on no brake light or taillights and have all new bulbs stupid. Turn headlights off brake lights work, so figure that out smart man
You could ride into one and smash it on purpose If you interrupted the flow of electricity to the lights they would not work. Ie, broken bulb, broken wire, blown fuse.
bad light switch.
There are several things that can cause your 2003 Kia headlights not to work. The most common cause is a loose or corroded ground wire.
There are several things that can make your headlights not work. First the might have blown a fuse, or maybe the bulbs burned out, or the battery might have died.
Faulty ground to the dash.
If it's an electronic (analog) speedometer needle, you probably have a problem with the dasboard grounding.
Many Camry models have so called daylight headlights.
If by "dim headlights" you mean low-beams... the bulbs are bad and must be replaced.
You probably won't have dash lights either. The problem will probably be at the light switch. If you take out the switch, there will be a burnt wire, and the switch will have to be replaced, along with a pigtail for the burnt wire.
i think, depending on the year, that problem is caused by a factory defect.
Headlights need to be on for starters. Blown bulb, relay, or switch.
fuse, swich, cut wire or the flasher could be out. iwould put my money on the flasher.
A short in the low beam circuit.
there are several possibilities, first: the fuse that provides power to the headlights could be blown out. second: the headlights could be burnt out. the other possibilities would require a professional diagnostics by a Subaru technician.
either both bulbs burnt out highbeam only or you need a headlight switch (controls signals, cruise(if it has it), and headlights)
check your bulbs. if a bulb blows they won't work.
Most likely a fuse.
my headlights work but my taillights and dash light dont work whats wrong
a weak battery would most likely be the problem. if that doesnt work, have your alternator checked.
