I want to hardwire an LED kit with switch to the household wiring? Answered

I've found similar instructions online but not quite the same thing I'm wanting to do.  Essentially, I want another fixture in the bathroom without using the plugins.

I have an LED kit with switch included.  (http://www.amazon.com/gp/product/B00UL2KKBQ?psc=1&redirect=true&ref_=ox_sc_act_title_1&smid=A3QAWKW1O2SEC3) I want to put the LED strip lighting under the bathroom sink vanity for subtle lighting in the middle of the night.  I want to set up the on-off switch at floor level to be poked with a toe.  However, I do not want to have a wire running from under the cabinet, across the wall to the plugin.

Is there a way to hardwire this LED kit into the house wiring that is already present?  NOT where an old fixture was, this will be all new wiring.  Thank you.

Even sources that might help me would be appreciated.


Why not use a free standing battery driven LED light, you could alter it to be motion sensitive and the battery would last for years.

That was my next choice. I like the motion sensor idea. Tell me more about this option. Could it be set up to only turn on when it's dark? I have other nightlights like that. What supplies would I need for the battery pack, wiring, connectors, etc? I've seen motion detector parts but not sure about the motion/night combo.

Something like this


will detect IR radiation from a warm body it will also have a sensor to detect light dark, they are generally used to turn on security lights so will have no problem with a few LEDs, they are mains powered though. You could put this in the corner of the room.

Remember that building codes for bathrooms are fairly strict as to what is allowed electrically.

i go with the leave the LEds on all the time you will never notice the electricity they use.

Well, if I go with the battery pack option, I don't think I need to worry much about regulations. It would be the same as having a nightlight like I have placed in the hall. Since there is no plug in, I bought a motion, nightlight, battery operated. I have no idea how much power it will need in terms of batteries nor do I know how to go about doing that but it will be a good project to research. Thanks!

It is perfectly possible to splice the power supply for your new light into the wiring of the existing light.

However, unless you are "competent" (ie have some relevant training or experience in domestic cabling), it is likely that doing so would invalidate your home insurance. In the UK, "new" electrical works (where you're not just replacing an existing fitting) require inspection by a qualified electrician before they can be switched on.

Since you are on a DIY site, effectively asking how to connect two wires together, I would respectfully suggest that you do not possess the required competence, and should at least consult a local professional with knowledge of local building regulations.

I hate dealing with electricity. I am not about to attempt this on my own but more want to know if this can even be accomplished and how much of the new wall I just had put in will be torn up. Ie. This is what they will do.. There are a lot of projects on this site that are above my abilities. I'm not stupid. I do as much as I am capable on my own house but big projects are left up to professionals. I have to have an electrician come in for another job and want to make sure this project is possible and make sure I have the supplies they will need to put it in for me.

Oh, it can be done, but without knowing *exactly* how things are set up, nobody here can predict how much wall will need torn up - it could be as little as a patch the size of a light switch, but it could need a trench dug in the wall the full length of your room. Your electrician will be the one who can tell you properly.

(By the way, my use of the word "competence" was not meant as a reflection of your personal capacities, it's is a term used in the regulations that govern such things.)

Thanks for the suggestions.

With LED just forget the switch leave it on all the time 24/7 save needless complications.

I have an electroluminescent under my vanity for 11 years so far (works great) on one AC line...


What you have is called an "EL panel" and they use next to nothing compared to LED strips.
But even a single LED uses more than those panels ;)

Very true, they use less power then an LED, in the US they are called night-lights and plug directly into our 115 VAC 60 Hz line, which is why I use it 24/7 and it guides me to the sink and a room dimmer if I need a med or whatever anytime at night.... We found 3 LEDs were too bright and cast a light into our bedroom through the glass door...

These EL panels are the same as the lower voltage higher frequency rope lights.... See the magic wand...


You're missing my goal. I do not want to use a plug in nor do I want them on 24/7. The whole point of the project is to make a cool nightlight that can be turned on at floor level, not annoy the crap out of a sleepy person and not take up an outlet. I wasn't the strip to bypass an outlet and be powered by the house electricity.

I know about simple plug in nightlights...see the kit I left a link to. Hardwiring that kit is a little more difficult requiring wiring, probably soldering and holes in walls...

Get an electrician to check your existing bathroom wiring, he then can advise on the safe options of installing the lights into the existing wiring.
There are regulations in regards to power outlets and switches in "wet rooms" like a bathroom.
Better be save than sorry....
