Installing an above ground pool return jet light is probably the easiest way to transform your backyard without spending a thousand bucks or ripping a hole in your pool liner. If you've ever gone for a night swim and felt like you were paddling around in a dark, bottomless abyss, you know exactly what I'm talking about. Backyard floodlights are great for seeing your patio, but they don't do much for the water itself except create a harsh glare on the surface. That's where these little return jet lights come in to save the day—or rather, the night.
What's the Big Deal with Return Jet Lights?
Let's be honest, traditional pool lighting can be a total nightmare. If you didn't have a light built-in when the pool was installed, you're usually stuck with floating LED "disco balls" that look a bit cheap or magnetic lights that eventually slide down the wall. A return jet light is a whole different ballgame. It actually replaces the "eyeball" fitting where the water pumps back into your pool.
Since it's literally screwed into the plumbing, it stays put. It's flush against the wall, it doesn't get in the way of the vacuum, and it uses the existing hole in your pool wall. You get that high-end, "inground pool" look for a fraction of the cost and about ten minutes of work. It's one of those rare DIY projects that actually delivers on the promise of being simple.
How Do These Things Actually Work?
You might be wondering how you get power to something that sits inside a water return. Well, there are actually a few different ways manufacturers handle this.
The most common version involves a thin, flat power cord that tucks behind the light and runs over the top of the pool wall. Because the cord is so thin, you can barely see it once the top rail is back in place. You just plug it into a standard GFCI outlet, and you're good to go.
Then there are the "hydro-powered" versions. These are pretty wild—they actually have a little turbine inside them. As the water flows from your pump back into the pool, it spins the turbine and generates electricity to power the LEDs. No wires, no batteries, no fuss. The only downside is that they only stay on while the pump is running, and if your pump isn't particularly strong, the light might be a bit dim.
Lastly, you've got battery-powered ones, but honestly, those can be a pain because you're constantly taking them apart to swap out AAs. If you're going to do it, the corded or hydro versions are usually the way to go.
Why the Placement is Perfect
The return jet is usually positioned a few inches below the water line, which is the "sweet spot" for lighting. It's deep enough that the light stays submerged and glows through the water, but high enough that it doesn't just illuminate the floor. Because the water is constantly moving through the jet, the light catches the bubbles and the ripples, creating this cool, shimmering effect that looks incredible when you're sitting on the deck with a drink.
Setting It Up (Don't Worry, It's Easy)
If the thought of "pool plumbing" makes you want to break out in hives, take a breath. Installing an above ground pool return jet light is mostly just unscrewing one thing and screwing in another.
First, you'll need to block the water flow. Most people just use a winter plug or have a shut-off valve near the filter. Once the water stops flowing out of the return, you just unscrew the outer ring (the "eyeball" part) of your current return jet.
Then, you take your new light fixture, seat it into that same opening, and tighten it down. If it's a corded model, you'll tuck the wire along the wall and over the rail before you tighten everything up to ensure a snug fit. Once it's secure, you turn the water back on, check for leaks (there shouldn't be any if you kept the original gasket in place), and plug it in. That's literally it. No drilling, no cutting, and no calling a professional who's going to charge you $200 just to show up.
Setting the Mood with Colors
Most of these lights these days aren't just "on" or "off." They usually come with a remote or even a smartphone app. You can change the color depending on what you're doing.
- Electric Blue: This is the classic. It makes the water look crystal clear and very "high-end resort."
- Deep Purple or Green: Perfect for a Halloween party or just a weird, moody vibe.
- Color-Changing Fade: This is great for when you're just hanging out. The colors slowly cycle, which is weirdly hypnotic to watch while you're floating on a raft.
- Strobe/Flash: Probably best saved for the kids' birthday parties unless you're trying to turn your backyard into a 90s warehouse rave.
The remote usually works through the water, but sometimes you have to stand pretty close to the edge of the pool to get it to register. It's a small price to pay for being able to change the entire atmosphere of your yard with one click.
The Safety Factor
Aside from looking cool, there's a real practical side to this. If you have kids or pets, a dark pool is a hazard. Even if nobody is supposed to be swimming, having that glow in the water makes it much easier to see if someone (or something) has accidentally fallen in.
It also helps with "night vision" while you're actually swimming. It's much easier to see the ladder, the edge of the pool, or that random diving toy your kid left at the bottom when the light is coming from inside the water. It gets rid of those creepy shadows in the corners that make you think a shark has somehow manifested in your 24-foot round above ground pool.
A Few Things to Keep in Mind
Nothing is perfect, right? There are a couple of things you should look out for. First, make sure the light you buy is compatible with your specific return jet size. Most above ground pools use a standard 1.5-inch threaded return, but it's always worth double-checking before you hit the "buy" button.
Also, keep an eye on the brightness (lumens). If you have a massive 33-foot pool, one return jet light might not be enough to light up the far side. In that case, if your pool has two returns, you might want to get a matching pair.
Another tip: don't forget to take it out if you live somewhere where the pool freezes in the winter. The ice can put a lot of pressure on the light housing and snap the plastic or damage the internal LEDs. Just treat it like your pump and filter—bring it inside when the snow starts flying.
Is It Worth the Money?
In my opinion? Absolutely. You can find a decent above ground pool return jet light for anywhere between $50 and $150. When you consider that adding "real" inground lighting can cost thousands, this is a total steal. It's a low-risk, high-reward upgrade.
It changes the way you use your pool. Instead of the pool "closing" as soon as the sun goes down, you find yourself wanting to go out there at 9:00 PM just to see it glowing. It makes the whole backyard feel like an extension of your house rather than just a dark corner of the yard.
So, if you're tired of swimming in the dark or using those floating lights that always end up stuck in the skimmer, give the return jet light a shot. It's probably the best "bang for your buck" upgrade you can do this summer. Your midnight swims will never be the same, and honestly, you'll wonder why you waited so long to do it.
