Fog lights are a great do-it-yourself add-on for a car or truck. Same goes for relays, but they give you much more options for switch they only have to be rated to ~1amp to trigger the relay, not 30+amps to power the lights and other options. There are many different brands out there, so look for a reputable manufacturer. February 16, 2014 2:16 pm I am a big believer in having a bright red rear foglight on my autos. Would it be better to reverse them and have the new lights coming from the fuse-block and the switch wiring off the low-beam wire? Hi, I just installed a third 'spot' driving light.
If your vehicle is not already equipped with fog lights, you will be left installing them on your own, which will require a fog light wiring harness. Ensure a good connection by filing off any paint, rust, or grit from the earthing point. You may originate from a search engine, after that discover this site. With the wiring run to all the places it needs to go, I then tackled the mechanical installation. The fog lights are positioned first, the switch second, and the relay last. Stripping too much wire can be dangerous if the wire makes contact with a ground, which is often the frame. I have a light bar that came with a wiring harness and switch.
Solder the ballasts to the fog light connectors on each side of the car, paying attention to the colors of the wires.

They crimp correctly and make the wiring joint strong mechanically. No problem, we are here to help.
A test is in order before you use the lock ties and button everything up. I elected to tap into the circuit using a step-down butt connector, which allows for wires of different gauges to be joined. It needs to be near a 12V power source. A relay is no more than a switch that operates electrically. Some even include the kit with the product. Strip your insulation only as far as the terminal requires.
Get the whole story right now in this video. The rule of thumb is this: the fuse ought to be rated near 80% of the amperage of the wire. In fact, in many corners of the aviation world, soldering is not permitted by governing bodies. T-Taps come with low-end electrical accessories. It took him about 40 minutes to actually do it! Amps are a measure of current flow; volts are a measure of the force behind the flow of current.
Each light should also have a ground wire connected to an earthing point or the chassis. Crimping is the way they join wires. The way that the kit is wired it will come off the headlight fuse to the switch. Mount the relay in the same area as the circuit breaker, also using a self-tapping screw. When you need to cut through the dense moisture that makes its way into the atmosphere as fog while driving, fog lights can be one of the most valuable components of your vehicle. The last terminal on the switch connects to the power source. Relays are an important component in wiring fog or driving lights with a 30-60A draw.
Lighting tip three: Use a relay We put in a relay because A it came with the kit and B we hardwired right to the battery, which gives power to whatever is hooked up to it until that connection is broken. This article was very helpful, as well as were the critical comments. So, with that said, I am gonna trot out the Super-Exciting-Lemmy-Fun-Filled-Adventure article on lighting here, and hopefully one or two things jump out as helpful.

They should not to be confused with driving lights, which are extremely bright and reduce the vision when on in a condition with fog. It took me about 20 seconds to write that sentence. This is the only acceptable use for speaker wire in a motorcycle installation - tying fairings to a safe spot. The relay acts as an electrical switch that activates and draws power straight from a good fused battery connection and sends it to the lights or accessory. It is probably 14 gauge or 12 gauge. Fog lights are always on Fog lights that remain on at all times are another symptom of a problem with the fog light relay. Hook up the new connections and check to make sure that the fog lights turn on.
But in the wiring harness that originally came with it, there are three wires going to the factory switch. Now, wire one of the remaining switch terminals to your power source, and the other to your reverse wire. There are sharp folk out there! The relay location must be well protected. And except for primary circuits, those three sizes will cover just about anything you want to wire in a truck with an adequate safety margin. The is ideal for these type of configurations.
