Lighting is one of those things that can make a van feel like a cozy home or a cold metal box. The good news is that it's also one of the cheapest and easiest upgrades you can do. A $30 LED strip light can completely transform how your van feels at night - and the wiring is about as simple as electrical gets.
Best bang for your buck: Warm white (2700-3000K) LED strip lights along your ceiling or under cabinets. $15-30 for a full roll, runs on 12V, and makes the space feel immediately livable.
For a more polished look: Add a few LED puck lights ($3-8 each) for task lighting over your kitchen and desk area, plus a small reading light by your bed.
Don't overthink it: A dimmer switch ($5-15) and warm white LEDs will get you 90% of the way there. You can always add more later.
When you're planning your build, lighting tends to get pushed to the bottom of the priority list. You're thinking about solar, batteries, insulation, the big stuff. But once you're actually living in the van, lighting is something you interact with every single evening. Bad lighting - too bright, too harsh, or not enough of it - makes the van feel uncomfortable in a way that's hard to put your finger on.
The goal is to create layers of light that you can adjust depending on what you're doing. Bright task lighting when you're cooking or working. Soft ambient lighting when you're reading or relaxing. Maybe just a dim accent light when you're winding down for bed. In a house you get this naturally with different rooms and fixtures. In a van, you need to be a bit more intentional about it.
The great news: you can create really nice lighting in a van for under $100 total. This is one of the few areas of a build where the budget option actually works great.
Before you buy any lights, you need to understand color temperature. It's measured in Kelvin (K) and determines whether your lights look warm and cozy or cold and clinical. This is probably the single most important decision for your van's lighting, and it's one that a lot of people get wrong.
This is the warm, yellowish glow you'd get from a traditional incandescent bulb. It feels cozy, relaxed, and inviting. Think candlelight to warm living room. This is what most people should use for their main van lighting.
Slightly less yellow than 2700K, but still warm. A good choice if you want something that feels warm but a bit more "modern." This is also a great option and honestly, the difference between 2700K and 3000K is subtle enough that either works well.
This is a more neutral, office-like light. It's fine for task lighting where you need to see clearly (like over a kitchen counter), but as your main lighting it can feel sterile. Some people use 4000K for specific task areas only.
Blue-ish white light. This is what cheap LED strips often default to. It looks like a hospital or a gas station bathroom. Avoid this for your van unless you specifically want to feel like you're in a dentist's office at 10pm.
Common mistake: Buying the cheapest LED strip on Amazon without checking the color temperature. Many budget strips are 6000K+ (cool white) because that's cheaper to manufacture. Always check the listing and look for 2700K-3000K specifically. The $3 you save on a cool white strip isn't worth living in a blue-tinted cave every night.
LED strips are the backbone of most van lighting setups, and for good reason. They're cheap, flexible, run on 12V (so they wire directly to your house battery), and produce a nice even light. A 16-foot roll costs $15-30 and is usually more than enough for an entire van.
The adhesive backing on LED strips works fine initially, but in a van that sees temperature swings and vibration, it will eventually start peeling. I'd recommend using aluminum LED channels ($10-20 for a pack). These give you a clean look, a surface to mount the strip to, and a diffuser cover that eliminates the visible individual LED dots. It makes the light look way more professional. You can screw or VHB-tape the channels to your ceiling or under cabinets.
Another common approach is to run strips along the top of your walls where they meet the ceiling, hidden behind a small lip or trim piece. This bounces light off the ceiling and creates a really nice indirect glow without any visible light source. It's a small detail that makes the van feel much more finished.
Puck lights are small, round, surface-mounted lights that provide focused, directional light. They're great for task lighting - over your kitchen counter, above a desk or work area, or in a closet. Think of them as the "spotlights" of your van.
You can get 12V LED puck lights designed for RV/marine use for about $3-8 each. They typically draw 0.1-0.3 amps each, so even running several of them uses very little power.
The most common choice. Screw them to your ceiling, wire them to 12V, and you're done. Available in warm white. Look for ones with a built-in switch on the fixture itself for convenience.
If you're building out a ceiling panel, you can cut holes and recess these for a cleaner look. More work to install but looks more "finished." Popular in higher-end builds.
These require zero wiring - just stick them up with adhesive. Great for closets, storage areas, or if you're doing a simple build without a full electrical system. Downside is you have to replace batteries periodically.
I'd recommend 2-3 puck lights over your kitchen area and 1-2 over any desk or work surface. They're so cheap that there's no reason not to have a few extras. You'll appreciate having bright, focused light when you're chopping vegetables or reading a map.
A reading light by your bed is a small thing that makes a big difference in daily comfort. When one person wants to read and the other wants to sleep, having a focused reading light instead of flooding the whole van with your main lights is a game changer.
These have a flexible arm you can bend to aim the light exactly where you want it. Mount one to the wall next to your bed. 12V versions are available on Amazon - search for "12V RV reading light." These are my top pick for bedside lighting. They draw almost nothing (0.1 amps or less) and you can aim them so precisely that your partner won't be bothered at all.
If you already have USB outlets near your bed (and you should), a USB clip light is the easiest option. Clip it to a shelf or headboard, plug it in, done. No hardwiring required. The downside is another cable visible in your space, but it's very low commitment.
The budget option that honestly works surprisingly well. Hang a small hook near your bed, and hang your headlamp on it when you want a reading light. You probably already own a headlamp, and many modern ones have adjustable brightness and warm light modes. Cost: $0 (you already have the headlamp for camping).
Accent lighting isn't strictly necessary, but it's one of those small touches that makes your van feel like a home instead of a vehicle. Under-cabinet lights in your kitchen, a subtle glow under your bed frame, a warm strip behind a shelf - these cost almost nothing but add a ton of character.
This is probably the most practical accent lighting you can add. A short section of LED strip (or a couple of puck lights) mounted under your upper cabinets illuminates your counter space beautifully. It provides excellent task lighting for cooking while also looking great. A 2-3 foot section of LED strip costs maybe $3-5 and draws about 0.5 amps. Put it on its own switch so you can use it independently of your main lights.
A strip of warm LEDs under your bed frame or along the bottom of cabinets creates a soft glow that's perfect for navigating the van at night without turning on the full lights. Think of it like a nightlight. You can find your water bottle or your shoes without blinding yourself at 2am. This is especially nice if you're doing a lot of stealth camping and don't want bright lights visible from outside.
Wire different lighting areas on separate switches or circuits. At minimum, have your main ceiling lights, kitchen lights, and bed area lights on independent switches. This way you can have just the kitchen lit while cooking, just the bed area for reading, or a soft glow from accent lights for winding down. It's not much extra wiring and makes a huge difference in daily livability.
A dimmer is probably the single best $5-15 you can spend on your lighting setup. Being able to go from full brightness when you're cooking to a soft glow when you're relaxing is the difference between lighting that works and lighting that feels right.
Wall-mounted touch panels that look cleaner than a knob. Some have tap-to-toggle and hold-to-dim functionality. A nice middle ground between basic dimmers and smart controllers. Search for "12V touch dimmer" on Amazon.
These come with a small wireless remote so you can adjust your lights from bed. The receiver wires inline with your LED strip, and the remote communicates wirelessly. Being able to dim or turn off lights without getting up is genuinely nice in a small space. My personal favorite option for main lighting circuits.
Important note on dimmers: Make sure your dimmer is rated for the wattage of your lights. Most cheap PWM dimmers handle 8-10 amps (96-120 watts at 12V), which is way more than enough for LED strips. But double-check, especially if you're running multiple strips off one dimmer. Also, always use PWM (Pulse Width Modulation) dimmers with LEDs, not resistive dimmers designed for incandescent bulbs - resistive dimmers will cause LEDs to flicker.
Smart lighting has gotten really popular in homes, so naturally people wonder about bringing it into a van. Options like Philips Hue, WLED-based controllers, or WiFi-enabled LED strips let you control your lights from your phone, set scenes, change colors, and schedule on/off times.
My honest take: for most people, smart lights in a van are a solution looking for a problem. A couple of physical switches and a wireless RF dimmer give you 95% of the convenience at a fraction of the cost and complexity. Your van is small enough that reaching a switch is never more than an arm's length away.
That said, if you're a tech enthusiast and this stuff is fun for you, go for it. An ESP32 board running WLED firmware with addressable LED strips is a genuinely cool project that costs about $30-40 total in hardware. Just know that it's a want, not a need.
Van lighting is about as simple as electrical wiring gets. Everything runs on 12V DC, the power draw is minimal, and the connections are straightforward. If you can connect two wires together, you can wire your lights.
Every lighting circuit follows this path:
That's it. Positive from fuse box, through switch, to lights, negative back to ground. Every lighting circuit in your van is some version of this.
For lighting circuits, 18 AWG wire is fine for most runs under 10 feet with typical LED loads (under 2 amps). For longer runs or higher-draw circuits (multiple strips), bump up to 16 AWG. This is not a place where you need heavy gauge wire - your entire lighting system probably draws less than 5 amps total.
For permanent connections, solder and heat shrink is the gold standard. For connections you might want to disconnect later, use Wago connectors ($10 for a box of 20) or marine-grade butt connectors. Avoid cheap crimp connectors - they vibrate loose in a vehicle. If you do use crimp connectors, give every one a firm tug after crimping to make sure it's solid.
For most van builds, here's what I'd recommend as a lighting setup that balances cost, simplicity, and livability:
Main lighting: A run of warm white (2700-3000K) LED strip in an aluminum diffuser channel along your ceiling. Wire it through a wireless RF dimmer so you can control it from bed. Total cost: about $30-40.
Kitchen task lighting: 2-3 surface-mount LED puck lights under your upper cabinets on their own switch. Total cost: about $15-25.
Reading light: One flexible gooseneck 12V reading light mounted by your bed. Total cost: about $10-15.
Nice to have: A short accent strip under your bed frame or along toe kicks for nighttime navigation. Total cost: about $5-10.
Total for all of the above: roughly $60-90. That gets you a multi-zone, dimmable lighting setup that covers every scenario from cooking to reading to late-night stealth mode. You don't need to spend more than this unless you want to.
Start with the main ceiling strip and kitchen lights. You can always add the reading light and accent lighting later - the wiring is simple enough to add on at any point. Just make sure you run the wires for all your planned lighting zones before you close up your walls and ceiling.
