Two owners can install the same light kit and have completely different experiences, because lighting in a Tesla is not one problem. It is four separate problems in four separate places, each with its own mounting method, its own power source and — the part that catches people — its own fitment boundary.
This is a map rather than a review. Four locations, what is actually dark in each, and how the light gets there. Two of the four bolt on without wiring anything; one plugs into a USB port; one replaces a factory lamp. And one of them only fits the older cars, which is the single most expensive mistake available in this category.
1. Four Lights, Four Different Problems
The instinct is to treat these as one shopping category — "interior lighting" — and pick the one that looks best. That works until you order the ambient light strip for a 2024 Highland and discover it was never made for your car.
The four differ along three axes that matter more than appearance. Where the light comes from decides how much wiring is involved: a USB port is nothing, a factory connector is a clip, and a hard-wired strip is a job. Where it mounts decides whether you need tools. And which model years it covers decides whether you can buy it at all.
| Location | Problem it solves | Power | Tools |
|---|---|---|---|
| Frunk | Unlit compartment, black bag on black floor | Factory connector | None — card-in fit |
| Trunk | Same problem, larger space | Factory connector | None — no glue, no screws |
| Dashboard | Flat, unlit interior at night | USB port | None — stick-on strip |
| Puddle | No light on the ground where you step | Replaces factory lamp | Pry tool |
Nothing on that list requires cutting a wire or drilling a hole. That is genuinely unusual for automotive lighting and it is the reason these four are worth grouping — they are all reversible, which means none of them is a decision you have to be certain about.
2. Front: The Frunk
The frunk is the original problem: a deep compartment with a light that does not reach the bottom, so anything dark-colored becomes invisible the moment the lid comes down. We covered the frunk strip in detail already, including how the plug-and-play connector works and why the strip fits without adhesive: lighting the cabin's darkest corner.
Rather than repeat it, the only thing worth adding here is the reason it opens this guide: the frunk was the first place Tesla owners noticed the problem, so it is the one location where the aftermarket has had years to settle. The frunk strip comes in white or yellow and its fitment is split by variant, so it is the one of the four where you select your model rather than confirming a range.
3. Rear: The Trunk
The trunk has the same problem as the frunk and a worse version of it. The space is larger, the single factory light is further from the far corners, and what tends to live back there is luggage — which is dark, bulky and exactly what you cannot find by feel.
The trunk LED strip is 5 m of silicone-encased strip at 12 V, and it installs in a way worth describing precisely because the product page compresses two separate things into one sentence. Electrically, a dedicated plug connects to the car's original interface — no rewiring, no drilling. Mechanically, it holds in place by fitting into position with a custom-molded shape — no adhesive, no screws.
Those are two different mechanisms solving two different problems, and together they are why this one needs no tools at all. Nothing is stuck to a surface that will get hot and let go, and nothing is screwed into trim that will crack.
Four colors are offered: white, warm white, red and blue. The first two are the practical choice for seeing what is in the box. The last two are not — they are for the effect, and the product page is honest about that, describing the soft light as useful for holiday surprises and photo fill as well as for visibility. Fitment is 2021–2026 Model Y and Model 3 Highland, so this is one of the three that covers the newer cars.
4. Inside: The Dashboard
This is the only one of the four that is purely aesthetic. Nothing is hard to find in a Tesla interior at night; the center screen lights the cabin adequately. What the dashboard strip adds is atmosphere, and it should be judged on that basis rather than on usefulness.
It is a 5 m strip at 12 V drawing 5 W, controlled through a dedicated app that handles brightness, color and effects, with up to 100 colors available. The feature that distinguishes it from a cheap static strip is music sync — the lights pulse and shift with the music or with your voice. Power comes from a USB port, which is the whole reason it needs no modification to the car's wiring.
The product is sold in four configurations, and the difference between them is what else gets lit: the dashboard strip alone, the strip plus a wireless charger, the strip plus four footwell lights, or all of it together. That progression is worth thinking about before ordering rather than after, because the footwell lights are the part that changes the feel of the interior most — a lit dashboard with dark footwells reads as partial.

5. Outside: The Ground Beside the Door
The fourth location is not inside the car at all. It is the patch of ground where you put your foot when you open the door in the dark — and in a Tesla, the mirror puddle light that should illuminate it is a small, unremarkable lamp.
The angel wing welcome lights replace that lamp and project a pair of wings onto the ground beside the doors. The install is a genuine direct swap: pop the factory puddle light out with a pry tool, clip the new module into the original connector and housing, done. No wire cutting, no drilling, no coding, five to ten minutes per side.
The detail that makes it feel factory rather than aftermarket is the timing. These do not have a switch or an app — they follow the car's own welcome-light logic, roughly 30 seconds on unlock, 3 seconds on lock, and 20 seconds in reverse. That means they behave like something the car already had rather than something added to it.
The hardware is more serious than the effect suggests: high-brightness SMD LEDs at 6500K drawing 2 W, an aluminum substrate heat sink, a coated high-transparency lens, flame-retardant ABS, and an IP68 rating that specifically survives car washes. Fitment covers 2021–2023 Model 3, 2021–2024 Model Y, 2024 and later Model 3 Highland, and 2025 and later Model Y Juniper — the broadest coverage of the four.
On the warranty question the page makes a claim of its own — that because this is a reversible, non-destructive swap, it typically will not affect the factory warranty, and suggests keeping the original lights to swap back before a service visit. That is the manufacturer's position, not a guarantee, and what actually applies to your car is a question for Tesla.

6. All Four Compared
Here is the whole set on the dimensions that decide a purchase, using each product page's own figures.
| Specification | Frunk strip | Trunk strip | Dashboard | Puddle lights |
|---|---|---|---|---|
| Covers Highland | Yes, by variant | Yes | No — 2021–2023 only | Yes |
| Covers Juniper | Yes, by variant | Yes (2021–2026 Model Y) | No | Yes |
| Power source | Factory connector | Factory connector | USB port | Replaces factory lamp |
| Adhesive or screws | Neither | Neither | Adhesive strip | Neither |
| Tools needed | None | None | None | Pry tool |
| Color options | White, yellow | White, warm white, red, blue | Up to 100 via app | Cool white 6500K |
| Control | Factory door logic | Factory logic | Dedicated app, music sync | Factory welcome timing |
| Water rating | Sealed silicone | Silicone, waterproof | Not stated | IP68 |
| What it changes | Visibility | Visibility | Atmosphere | Arrival |
The dashboard column has the most "not stated" entries, and the fitment row is why. It is the only one of the four limited to the pre-Highland cars, and it is also the only one that gets its power from a USB port rather than the car's own harness — which is a neat solution and also why it does not need any model-specific connectors. The trade is that there is nothing to connect it to on a newer car's own lighting logic.
7. What to Buy First
If you are buying one, buy the one that stops you hunting for things. That is the trunk on a Model Y, because the space is largest and the factory light reaches the least of it. On a Model 3 sedan the trunk is smaller and the frunk may bother you more.
- Practical first: trunk or frunk strip. Both are tools-free, both solve a real problem, both are reversible.
- Comfort second: the puddle lights. Not a visibility problem, but the one that changes how the car feels to approach.
- Atmosphere last: the dashboard strip, and only if you own a 2021–2023 car. On anything newer it is not an option.
- Before any of it: confirm your model year against the fitment row. Three of the four cover the new generations and one does not, which is not the pattern anyone expects.
8. Frequently Asked Questions
Will the dashboard ambient light fit my 2024 Model 3 Highland?
No. It is listed for 2021–2023 Model 3 and Model Y only, with no Highland or Juniper version. This is the one product in this guide that stops at the older cars — the trunk strip and the puddle lights both cover the newer generations, so the mismatch is easy to miss.
Do any of these require cutting or drilling?
None of the four. The frunk and trunk strips connect to the factory interface and hold by molded fit; the dashboard strip takes power from a USB port and adheres; the puddle lights are a direct swap of the factory lamp. All four are reversible.
How long does the trunk strip take to install?
It needs no tools at all — no adhesive and no screws, with a dedicated plug into the car's original interface and a custom-molded shape that holds it in position. The product page does not state a time figure, but nothing about the method requires disassembly.
Do the puddle lights need coding or a switch?
Neither. They follow the car's own welcome-light timing — roughly 30 seconds on unlock, 3 seconds on lock, and 20 seconds in reverse — so there is no app and no separate switch. Each side takes about 5–10 minutes with a pry tool.
Are the welcome lights safe through a car wash?
They are rated IP68, which the page describes as dust-tight and sealed against rain, puddles and car washes. The lens is coated high-transparency material and the heat sink is aluminum substrate, so the assembly is built for outdoor exposure rather than protected installation.
Which one should I buy if I only want one?
The trunk strip on a Model Y, because the space is largest and the factory light reaches the least of it. On a Model 3 the trunk is smaller, so the frunk may be the more frequent irritation. Both are tools-free and reversible, so neither is a decision you need to be certain about.
9. The Bottom Line
Lighting in a Tesla is four problems, not one, and they are solved in four different ways. Two are about finding things, one is about atmosphere, and one is about the moment you walk up to the car. None of them needs a wire cut, which makes all four low-risk.
The one thing that does carry risk is fitment, and the pattern is not what you would guess: the practical strips and the puddle lights cover the current generation, while the ambient strip stops at 2023. Confirm your model year before anything else, and the rest is a question of which annoyance you would rather stop living with.
Disclaimer: Fitment varies by model year and trim. Confirm your vehicle against each product's compatibility list before ordering, and check with the seller if your car has optional mirror functions such as auto-dimming or heating. All products here are reversible additions and none should be installed in a way that interferes with factory lighting or safety systems.
