A relay is an electrical switch that lets a low current circuit control a high current circuit such as a large LED light bar. If you are using a light pod that does not have a very large amp draw, you may not need a relay switch, but if you are using a larger LED light bar, they are a must have.

Why do I need a relay for fog lights?

Relays are an important component in wiring fog or driving lights with a 30-60A draw. Basically, the relay protects the switch from getting hot and creating unwanted resistance. The low current through the switch triggers the relay to make a higher current connection to the heavy load of the fog lights.

Can I install fog lights without relay?

the easiest way i found for the install is to mount your fog lights and ground the ground wire to the chassis. the hot wire(power) you can run to your stock low beam wires (on BOTH sides) this draws the power from each of your low beams to power the fog lights also.

Is there a relay for fog lights?

The fog light relay is the electrical relay that is responsible for controlling power to the fog lights. When the fog light relay fails or has any issues, it can cause problems with the operation of the fog lights.

Do LED lights need a fuse?

These LED lights draw less amps than your standard incandescent lights. You should not need a circuit breaker of in line fuse. These lights draws only 0.6 amps. However, you can install an inline fuse if you feel that you need one.

Can fog lights drain your battery?

Seems a bit early for a battery to need replacing, but it is possible. Infinitis are well known for playing tricks when the battery gets low on cranking amps. Its possible the battery is not dead, but is too weak to start the engine with any extra drain pulling amps from it.

Do relays have to be grounded?

The relay must be on the ground side of the load when the voltages above the coil are hot. The case should be grounded. The relay can be on either side of the load for hot switch voltages that are lower than the coil.

What does the fog light symbol look like?

The symbol youre looking for is a lamp pointing to the left plus a wavy line with three lines through it - these are your front fog lights. When you turn on your rear fog lights a lamp pointing to the right plus a wavy line with three lines through it will appear on your dashboard.

What amp fuse should I use for LED lights?

75mm is good for about 7.5 amps max. I generally like to have at least 100% extra rating so a 3 amp fuse max is what i would use. This should be plenty for 4 leds. If you have working leds but blow a 10A fuse i think your wiring needs checking and you will probably find your fuse is directly across the battery.

Can you run LED lights off a battery?

Most LED lights are arranged so that they can run off of a 12v battery—in fact, 12v lights can cause a short when plugged directly into a socket, which usually have 110v current. This can be very dangerous, and so the best solution is to run these lights through a relay instead.

Should I use my fog lights all the time?

If you leave your vehicles fog lights on all the time, some might call you a jerk, and one driving expert says it can be downright dangerous, so cut it out.

Can you drive with fog lights all the time?

A: Yes, it is legal if the lights are within the proper height and aimed within the legal range. I recommend that fog lights be used only in low-visibility settings, as some of them can be hard on the other drivers eyes.

What is a ground trigger?

Circuit 6 is set to “ground trigger.” A door switch connecting to ground could be used to turn on an interior light when the door is open even if the ignition is off.

Can you wire up spotlights without a relay?

If your spotlight did not come with an electrical relay, you will need to install one. Most stoplights should not be wired directly to a power source without being run through a relay. If your kit did not come with one, purchase a SPST (Single Pole Single Throw) Relay from your local auto parts store.

How do I know if my fog lights are on?

Which symbol is for fog lights? When you turn on your fog lights a symbol will light up on your dashboard to show that theyre on. Usually, the indicator for the rear fog lights is amber and the light for the front fog lights is green.
