I did not get an install guide. Where can I find it?

Every install is different so we do not include a guide in the boxes. 

Our website has helpful blog posts and customer installs that can be used as guides. Click here to see customer installs. 

Our Wiring Diagram is also very helpful as a visual guide on how to wire numbers into your electrical source using jelsco LED drivers.

Should I use the screws or dowels included with my number?

Mounting options:

Each number comes with two metal dowels and two screws with stoppers.

  • The dowels are great in instances when you cannot access the interior/backside of your mounting surface. Simply drill a hole using a 5/32 drill bit. Then, with the dowels attached to your number, firmly press it into your surface. With the right drill bit the fit should be snug, but not too tight (do not use a hammer to tap in) Glue can be used in the holes for an extra-strength hold if desired.
  • The screws work well when you have access to the back/interior of the mounting surface, such as a plaque or open interior wall. When mounting on a thin surface, the rubber stoppers can be used to prevent accidentally screwing into the numbers too far and damaging the LEDs. Please note that the rubber stoppers are not intended to be used as stand-off mounts. Our numbers look best when mounted as flush as possible.


Can I mount the numbers stand-off?

We always recommend mounting the numbers flush for the cleanest look and smoothest light output. 

Their thickness already provides a nice 3D effect that one wishes to get with stand-off mounting. 

Stand-off mounting creates the issue of exposed wires and choppy lighting. 


Is installing the numbers DIY friendly?

This depends on your level of experience. Suppose you are uncomfortable with electrical work, we strongly recommend hiring an electrician to install your house numbers. Each LED house number is essentially an outdoor light fixture and will be installed the same way.  

We carry plug-in LED drivers in addition to our wire-in drivers. Plug-in drivers are much more beginner-friendly. All you need is an outlet (preferably waterproof if using outdoors)

Sadly, we’re unable to add or modify order details once we’ve started processing them. If the order has not been processed by our warehouse, we will need to cancel and replace your order with the correct information. Please contact us as soon as possible via info@jelsco.com

How do I cancel my order?

There is only a short amount of time between when you place your order and when we start processing it.

If not, we’ll despatch your order and then you can return it to us if you wish upon receiving it.

Can I request a custom order?

Numbers can be customized. Our minimum order quantity is 30+ for customizations. Contact us by email at info@jelsco.com to learn more.

LED Numbers

Can I get the Neutra/Arial fonts in a different color?

No, not unless you are placing a custom order with a 30 item minimum.

At this time we only offer the two lines of numbers in the colors they are. 

Are the lights dimmable?

Yes! The LEDs are dimmable and it is easy to do with our LED drivers, which come with a dimming switch.

If you do not need a driver you can also just buy a dimmer from us. Both options are available through this link

Do they automatically turn on when it gets dark?

No, but it is possible! To do this, you need to wire in a "Dusk To Dawn Light Sensor Switch " aka Photocell sensor. 

The other option is putting the numbers on a timed on-off switch or smart switch to create a routine.

How do they hold up in coastal areas?

Even though the numbers are made of stainless steel they are not 100% rust-resistant to the salty air in coastal areas. We suggest you place an extra seal around the cracks to ensure that saltwater does not make its way inside the numbers where it can affect the wiring. Clear Marine grade silicone will do the trick. 3M 08019

LED Drivers

Do I need an LED driver for each number?

No. One of our drivers can power up to 7 of our 12" numbers.

You will know when a LED driver is overloaded as the numbers will start flashing or turning on and off.

If I already have a 12V wire in place, do I need to buy the transformer?

No. As long as it is 12v DC (NOT AC) and 1 Amp you can use your own.

Returns and Exchanges

Can I return or exchange an item?

Yes. We are able to accept returns within 45 days of your original purchase date for a refund if the item(s) are unused and clean with the original packaging. We cannot accept items with scratches, dents, or signs of weathering.

This depends on the carrier or shipping method that you choose when returning your item.

Warranty related FAQs

How do I file a warranty claim?

The first step in a warranty claim is to send an email to Info@jelsco.com. We will need pictures of the damaged/faulty product with a short description of how it happened. If you really want to make it an easy process please include: the order number, first and last name of the purchaser, color and size of your item, and a ballpark of when the item was purchased. That will make it easy for us to find the original order.

If my number rusts is that covered under warranty?

No, rust is a natural occurrence, even on stainless steel, which is resistant to corrosion due to its native protective layer (chromium oxide). Our numbers may require a small amount of maintenance to keep your numbers from rusting, such as cleaning and applying protective barriers. This is more of a concern for coastal zones with high humidity and salinity. Customers living in these environments should take extra precautions to ensure the longevity of the stainless steel and keep it looking good.

  A quick google search will turn up many products that will help protect your numbers.
