Stair Riser Lights: Should You Install One or Two per Step?

code requirements for stair lighting

Stair riser lights are one of the best add-ons you can install on your deck. 

If you’re sitting in your backyard on a patio or next to your deck, they create a beautiful, warm, and inviting glow. Also, riser lights make it exponentially safer to use deck stairs at night. In our eyes, there’s no doubt that lighting up your deck stairs is a worthwhile investment. 

But the real question lies in how many lights you should install per step. And what other customization options do you have when it comes to design and budget? 

Let’s dive in. 

A Word on Building Codes

In many cases, adding stair riser lights isn’t required by code but many municipalities require that you illuminate the top and bottom of your deck’s stairs. But more often than not, a single wall sconce on the back of your home near your door will do the trick. Of course, you’ll want to check in with your local municipality to find out the laws in your area.

Even if there’s no requirement, there’s still a safety factor to consider. And adding riser lights makes your stairs and deck safer for everyone who uses it.


Also worth mentioning, if you have a multi-level deck, we highly recommend installing riser lights between the connecting stairs. That way, when you and your guests are out at night, you’ll safely know where the steps are between the tiers. And this is particularly handy when you’re not yet familiar with the layout of your deck.

One Vs. Two Lights Per Step

Now we have that covered, let’s jump into the common question of installing one or two lights per riser. What we recommend depends on the width of your stairs. 

One Light

It’s most common to install a single light per riser on any standard 4-5 foot wide set of stairs.

Two Lights

Any stairs wider than 5 feet, we typically recommend installing two lights. Not only for aesthetic reasons but again for safety and to ensure proper illumination of the entire step.

But if we’re strictly talking visuals, two lights per riser on any width of stairs looks absolutely stunning! (The photo above with two lights per riser is a 4′-wide set of stairs.) If the investment is within your budget, it’s one of the best upgrades to your deck to make it “pop” and stand out. 

Lighting Every Second Step

Another common question homeowners ask is if we can install riser lights on every other step instead of every step to save a bit of money.

While this is possible, it’s not always ideal. Riser lights are designed to illuminate their respective step, but not the next one down. So the angle of the light won’t quite reach the step below, and it will remain dark. 

Double Lights

Interestingly enough, we also get asked about installing two riser lights on every other step; in these cases, it’s usually more about design than budget. But for the safety concerns we spoke about above, we still recommend installing one light per riser. Considering it would be the same investment as two lights every other step. 

However, if your heart is set on skipping steps, we recommend also installing railing post cap lights or post sidelights. That way, your stairs will still have plenty of light at night.

Colors & Brands

Continuing with aesthetics, most manufacturers of stair riser lights make the housing (the visible part that the bulb sits in) available in shades of white, black, and brown. We typically recommend matching the color to a component from your railing to tie the entire design together. But, if your fascia is white, opting for white housing is also an excellent choice for a clean and sleek look.

PRO TIP: Light Brands

When your contractor offers you stair riser lights, be sure to have the brand written into your proposal. It’s not uncommon for builders to install an off-brand light that may be cheaper and lower quality. 

The two brands we use and recommend are Trex and LMT Mercer, but there are plenty of other good companies out there. 


Stair riser lights contribute to both the safety and the overall aesthetic of your deck design. While there are general guidelines we recommend following, the “correct” amount of lights per step isn’t set in stone. Work with your deck builder to find a lighting design you love that also keeps your stairs fully illuminated and safe for you and your guests.

Lumber and Trex Market Costs Update

Last Updated: 1/29/2022
Custom Deck Creations

A brief look into the current and expected inflation

Quick Summary

Lumber rose +28% locally from November 2021 to January 2022, and is expected for another significant double-digit increase impacting us in June 2022. We’re also anticipating a cost increase  from Trex around that  same time frame. Depending on size and material selection, decks are anticipated to increase in cost an average of $2,000 to $4,000 come June 2022. Custom Deck Creations is currently scheduling projects for April/May, before we feel these cost increases. Schedule a quote with us today to lock in today’s costs.

For a more detailed look into the market, please continue reading:


The lumber market continues to see pressure on the supply side. Canadian truck drivers are protesting COVID vaccine mandates, threatening to disrupt deliveries in Canada and possibly into the US. Fuel prices are also increasing. Overall demand for Southern Yellow Pine (pressure treated lumber used here in MI) remains steady. Mills are not sitting on a lot of inventory. Lead times from mills to dealers are getting extended.

Pressure treated lumber costs increased locally +28% from November 2021 to January 2022.

Lumber is expected to increase another ~+40% in June 2022. 

Custom Deck Creations is currently scheduling projects for April & May 2022, before we’re impacted by these increased costs.


Data from Trex distributors nationwide are seeing a steady growth in purchases even through winter.

Trex continues to see huge demand increases nationwide. 

Our Interpretation

Lumber will continue to rise in price throughout 2022. We don’t believe we’ll see pre-2022 lumber pricing any time soon.

In 2021 Trex put out 4 separate approximately +10% price increases. We believe more are to be expected in 2022. We do not expect Trex to ever lower their pricing.

No Inflationary Clause

Custom Deck Creations does not have an inflationary clause. Lock in today’s lumber and Trex costs with a signed agreement which puts you on our schedule. We will not charge you more even if our costs go up.
