On the left handlebar the beam switch has an input wire and 2 outputs. The yellow output is low beam and the white is high. The wiring harness exits the switch housing and resides in a dimple on the bottom side of the handlebar. This is a very easy place to pinch a wire. Have you replaced grips or installed chrome switch housings? Yank the connectors off the headlights and try it again. If you have a broken filament that is touching the other filament it will draw way too much current, and if it doesn't kick with the lights unplugged then one or the beams is bad. One other thing that is rare: I have seen a failed dimmer switch turn on high and low beam at the same time. Temporarily install a higher amperage fuse that won't blow and look at the filaments through a welding hood to see if they are both on. Do this last.

Where is the headlamp relay on a 2007 saturn ion


Are both low beams an high beams not working ? What engine does your car have ? Low beam relay only on 2.2 L .
On vehicles with manual headlamps, the LH HDLP and RH HDLP fuse in the fuse block - under hood, supply battery positive voltage to both low beam lamps and high beam lamps at all times. The low beam and high beam circuits continue through the fuse block - under hood, through the body control module (BCM), and to the headlamp switch. The low beam or high beam circuit then, depending on the position of the dimmer switch, continues through the headlamp switch. When the headlamp switch is placed in the ON position, it provides a ground path for the low beam or high beam lamps through G203. The low beam and high beam circuits are monitored by the BCM.
Is there B+ voltage at the headlamp fuse's ? Power runs from fuse through the head lamps to the dimmer switch through the head lamp switch to ground when turned on . If there is B+ voltage at the fuse ,check for voltage at the headlamp switch .

No headlights on dim only work on bright


old post.(day)
low beams, they are.
both low beam lamps.dead but are PARK/tail dead too?. (a key fact needed here to save time finding cause)
there are more that one cause.
but fuses are first, some cars have 2 fuse.
one for highs and lows.
or for left and right.
they do that so at least some lights work and not all go out at once, on a dark rainy night on a country road (or cliff road)
GEO, the car brand GEO is sold mostly in USA and Canada
if in CANADA the law says its DRL lamps.
in canada they have a Drylight Running lamps and laws and have a unique controller for that (DRL module) and can fail and mess up lamps. so GOT DRL>?
on this car the fues box shows, left and right HL
the next question is does it run a relay.
answer,
DRL, the DRL module runs low beams totally so that be first.
and its DRL relay.
non DLR metro, works like this
im reading the online schematics for you, and so could you.
the no-DRL is brutally simple.
the fuse runs the lamps direct, means lamps hot all the time.
the park and head light switch, grounds the low beam wire feed.
no relays , magic , DRL just a simple switch, in the combo switch.
for you or others seaching Metro head lamps.
here is the schemo.
red/wht wire must be 0v on low beams if not switch bad.
if g200 is good, but g200 is used in highs so can NOT BE BAD.
as you can see the switch grounds the HL lines below.
to make the lamps GLOW,

Main beam lights not working


check fuses, in cab and eng. bay.
high beam or low beam.
main to me, is low?
do you want to guess or diagnose?

do you have a voltmeter? a DMM or DVM. ?
with a meter, this is easy.
are both headlights dead?
does car have DRL? (in canada many cars have this, do you?)
Daytime Running Lights.?
the 2003 USA model, has a Relay control module under hood.
in your car all lamps are grounded and 12vdc power feeds
the lamps via 1st the control module then 4 fuse to the lamps.
as you can see 4 fuses, usually dont blow at once.
inside the module are 2 relays. one for low beam and one for high beams. they too can fail. so if lows are bad, replace the low relay.
if you get the FSM book for your car, its ALL there, ever fact on
this simple circuit and how to test it.... step by step.
never buy a car, with out the FSM, if a DIY person.
if not? take it to the man.....

You can't turn them on manually with the switch . You have the switch set on auto ?
Headlamps
You can use the headlamps in two different ways.
• Place the headlamp switch in the ON position for normal operation.
• Place the headlamp switch in the OFF position for automatic lamp control (ALC). During ALC the high beam headlamps are On at reduced intensity for daytime running lamp (DRL) operation in daylight conditions, or low beam headlamps On in low light conditions.
The DRL/EXT LTS fuse and the EXT lamps fuse in the underhood junction block supply battery positive voltage at all times to both of low beam lamps and to the right high beam lamp. The low beam circuit continues to the high/low beam switch, then, depending on the position of the dimmer switch, connects to the normally-open headlamp relay switch contacts. Placing the headlamp switch in the HEAD position provides a ground path for the headlamp switch input of the Body Control Module (BCM). After receiving this input, the BCM energizes the headlamp relay. When the headlamp relay is energized, the low beam circuit is connected to ground G201. The high beam circuit is divided into a left and a right side circuit.
The DRL/EXT LTS fuse in the underhood ignition block supplies battery positive voltage to both the coil and to the normally-closed contact of the DRL relay switch circuit. During high beam operation, the left side current flow is through the closed contacts of the DRL relay, and to the left high beam lamp.
The EXT Lamps fuse in the top of the engine fuse block supplies battery positive voltage to the right high beam lamp. Both high beam circuits are then connected together, and continue to the dimmer switch. When the driver closes the high beam contacts of the dimmer switch, the circuit is grounded at G201.
Both the headlight switch and the BCM provide a ground, or control circuit, to the headlight relay coil circuit for manual or automatic headlamp operation. When you place the headlamp switch in the OFF position, and the ambient light sensor indicates low light conditions, the BCM energizes the headlamp relay for low beam operation. You may switch the headlights to high beam by pulling the dimmer switch handle toward you until the dimmer switch is activated. When the dimmer switch is placed in the HIGH position, the indicator lamp input to the BCM is pulled low. The BCM then sends a class 2 message to the instrument cluster in order to illuminate the high beam indicator lamp.
If the headlamp switch is left in the head position, the inadvertent power control feature will turn off the headlights 10 minutes after you turn the ignition switch to the OFF position. If you place the headlamp switch in the head position after the ignition switch has been turned OFF, or if the ignition switch is in the ACCY position, the headlights will remain ON until you turn them OFF or until the battery runs dead.

Well the high and low beam lamps use the same fuses, and the dimmer switch handles the ground circuit. So I would check the dimmer switch if both high beam bulbs are ok.

Kia optima low beams


First verify that the switch is energizing the relay in both positions by turning the low beams on and then pulling up the relay--does it click? If not, replace the switch. If yes, next check for power on the red wire as it comes out of the column. Switch on, no power--replace the switch. If power, check for power at the head-low fuse in the engine compartment fuse box. No power--find break in wire. If power, check for power on the yellow/red wire as it comes out of the fuse box. No power--repair fuse box. Power--check for power at lamps--same wire. No power--repair yellow/red wire.
