Have a dirt bike with headlight. Three wires for hi/lo, how do I put two fog lights in place of that head light without too much wiring work. I don't need hi/lo option


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

99 grand prix gt low beam head light not working ,but high beam and fogs do


Hi Brian:
First thing I would do would be to check the bulb.

Next, Have a look at your fuse index.
There is a distinct possibility that these are on separate fuses and perhaps it's just a bad fuse.

No headlights or fog lights

99 E320 LOW BEAM, FOG, TAIL LIGHTS WONT SHUT OFF EVEN THE CAR IS NOT WORKING FUSES IS OK


Check the headlight relay under the hood in the fuse box. They will stick when they get old. The diagram in the fuse box lid will tell you which relay is the horn, headlights, etc.

High beam indicator comes on with fog lights


Could your Mazda have daytime running lights? If you checked all fuses, did that include the three in the joint box?

There is an auto light-off control module that is central to all functions you describe. It is assumed that you would only turn on the fog lights with headlights on and set for high beam. If you set the headlight switch to LOW, the module closes the headlight relay to turn on the low beams. If you then turn the headlight switch to HIGH, the module turns on the high beams and allows you to turn on the FOG LIGHT switch, closing the fog light relay and turning on the fog lights. Since this sequence is not working, I suggest checking both high beam lamps as both could be burned out. Other possibilities are a defective headlight switch or the module

Low beam dont work


usually both lights don't go at once so it is probably the resistor on the same circuit, probably just a fuse or relay! get a wiring diagram for illumination and test the circuit with a DVOM, bet you just have a bad connection, or loose wire, bad relay.....

I have no low beam, high beams work and also fog lights, my running light dont work either ?


Sounds like the relay for the low beams is bad, or the fuse is blown. But if both of them do not work it usually means the relay.

1999 grand am. low beams dont work. i checked all fuses and relays. ideas????


Lets start by checking the fog lamps. Turn the headlights on, switch to low beam, turn on the fog lights and see if they come on. If the foglights don't work, then you don't have voltage on the low beam circuit to the BCM. If you do have foglights, then the low beam circuit is providing voltage to the BCM.
By determining if the foglights work or don't work we will be able tell what side of the circuit we need to work on.
Let me know.
