Can you put a dimming switch on any light?

Dimming switches are a great way to save energy and extend the life of your light bulbs. But can you put a dimming switch on any light? The answer is maybe. If your light is compatible with a dimming switch, then you can probably put a dimming switch on it. But if your light is not compatible with a dimming switch, then you probably can't put a dimming switch on it. So how do you know if your light is compatible with a dimming switch? The best way to find out is to consult your light's owner's manual or contact

Do you need special wiring for a dimmer switch?

Dimmer switches are devices used to lower the brightness of a light. They are often used in living rooms and bedrooms to create a softer ambiance. While most dimmer switches will work with any type of lighting, some may require special wiring. Be sure to check the specifications of the dimmer switch before purchasing to ensure compatibility.

Does a dimmer reduce voltage?

No, a dimmer does not reduce voltage. A dimmer is an electrical device that is used to control the brightness of a light. By lowering the voltage, the dimmer reduces the amount of power that is sent to the light bulb, which in turn decreases the brightness of the light.

How do I know which dimmer switch to buy?

There are a few things you'll need to consider when purchasing a dimmer switch. First, you'll need to know the voltage of your home's electrical system. Most dimmer switches are designed for either 120-volt or 240-volt systems. You'll also need to know the wattage rating of the bulbs you'll be using with the dimmer switch. Another thing to consider is the type of dimming technology you want. There are three main types of dimming technology: leading edge, trailing edge, and universal. Leading edge dimmers are typically used with inc


Standard Motor Products DS70T Dimmer Switch Review:


I used this in place of my 1994 YJ's column-mounted bright switch since I like it so much more. The plastic column-mounted switch, which gets clogged up and breaks the turn signal switch, is made of plastic. decided to forego it and stick with the tried-and-true bright switch that is situated on the floor. similar to my vintage 1973 Pontiac Ventura! Much improved!



American Technology Components 12 Volt DC Dimmer Switch for LED, Halogen, Incandescent - RV, Auto, Truck, Marine, and Strip Lighting (Slider, Black) Review:


This high side dimmer is used. It is now situated in my Open Range fifth wheel's main salon. It regulates six 4W LED recessed ceiling lights. The installation process worried me, yet it was simple. But I made use of a voltmeter. All of the wires attached to the negative side (ground) are solid WHITE, and the wires connected to the hot side are WHITE/RED STRIPE, as I noticed after removing the top from the circuit breaker box. The WHITE/RED STRIPE, one of the two wires attached to the back of the existing on/off switch, is practically identical to the other wire. That wire carries power. The two wires come from the breaker box, which supplies power, and the other is connected directly to the lights if you take those two wires out of the switch. The voltmeter is useful in this situation. The wire that originates from the breaker box must be identified as ONE of the two wires. The hot wire is there. That wire should be connected to the RED wire on your new dimmer. The other white/red stripe wire that you removed from the first on/off switch should be connected to the WHITE wire from your dimmer (the one that continues to the lights). Find the white wire that is next to the white/red stripe wire and connect it to the BLACK wire on your dimmer. This white wire is the negative (ground) wire. You've joined a 3 wire dimmer to a 2 wire switch. Despite being connected at the original on/off switch by being pulled away, the white/red stripe and the white wire are essentially one wire (two independent wires bundled together). I was fortunate to discover the white negative/ground wire already cut and with its two ends secured by a wire nut. I tested the voltage by inserting the voltmeter's BLACK lead into the wire nut containing the spliced white wires and the RED lead into each of the white/red striped lines, then seeing which one displays 12 volts. No reading will be done by the person who goes to the lights. And that is 12 volt dimmer wiring for beginners. For all of us with electrically challenged souls, I hope this makes things plain. The wires to the right of the blue blade breakers are White/Red striped, as seen in the photo of the breaker box. If you need to see inside your RV's circuit breaker box, always shut off the circuit breaker at the pedestal first.



American Technology Components 12 Volt DC Dimmer Switch for LED, Halogen, Incandescent - RV, Auto, Truck, Marine, and Strip Lighting (Large Slider, Black) Review:


To dim 8 overhead LED lights in a 2017 Grand Design Solitude, I purchased this switch. The existing switch only had two wires connected to it, so even though the instructions sounded simple, I was unable to connect it. The manufacturer used white wire, which is the color of the ground on my equipment, as a jumper between two neighboring switches for the 12v power in, further causing confusion. I told the seller that the switch was broken when I spoke with him. They sent me another one soon away, which was quite helpful. Since I wired the second one incorrectly, it initially didn't work either. When I eventually looked at another switch controlling a single light, I realized how to correctly connect it. To pay for the second switch, I emailed the vendor, but I haven't heard back yet. I don't mind that the lights are not completely dimmed by this switch. And when darkened mid-range, they do have a very, very small whine, but you really have to listen for it. The product, the outcomes, and the customer service have all exceeded my expectations. And so will you. PS: In my bedroom, I utilized the original dimmer, and it works flawlessly!

ACDelco D808 Professional Headlamp Dimmer Switch Review:


Fit perfectly and was immediately plugged in! 3/4 Ton 350/TH400 on my 1969 Chevy C20 CustomCamperDue to their frequent contact with the floor and the proximity to my truck's floor vent, these switches frequently accumulate a lot of dust and grit. This new switch seemed... a little worse for wear, I suppose. Being that I prefer everything to be constructed like a tank, I installed it and it was flawless! The truth is that, like with most products for my 69-year-old, I ordered a second one to have on hand. Furthermore, I have no memory of ever using the dimmer switch. I purchased a new dimmer switch after pushing the old one by hand while cleaning the carpet in the garage and realizing how hard and clunky it felt.I'm delighted with this switch because it serves my purpose and has a small number of uses.Mark/Ragen Rat
