FEAOXYO vs Feikenee Test Light: Which Circuit Tester to Buy?
FEAOXYO Test Light Automotive is the better pick for most buyers because of its longer 39-inch PU wire and stainless steel probe, while Feikenee Test Light Automotive suits anyone who wants a more compact tester with a reinforced steel and AS build. Both cover a 6-24V DC range, but FEAOXYO pairs its 39-inch wire with a non-slip handle, and Feikenee lists an 8.47 x 3 x 1.26 inch body with a 39-inch wire of its own.
- Choose FEAOXYO Test Light if you want a flexible PU wire and a long stainless steel probe for piercing insulation in tight spots — it carries a 39-inch PU wire and a 6-24V DC range.
- Choose Feikenee Test Light if compact storage in a toolbox matters most — its body measures just 8.47 x 3 x 1.26 inches with a 39-inch wire.
I compared these two test lights on voltage range, probe and wire design, and body dimensions, using the listed specifications for each. Both run on a battery-powered setup with a 6-volt minimum and 24-volt maximum.

Individual Product Breakdown
I looked at the same three things for each test light: the voltage range, the probe and wire setup, and how compact the body is. Here’s how each one holds up in real use.
FEAOXYO Test Light Automotive

I like this one because the 39-inch PU wire stays flexible in cold weather and the non-slip handle gives me a firm grip when I’m reaching under a dash. The long stainless steel probe pierces insulation easily, and the bulb brightness changes with the voltage so I can read circuit conditions at a glance. It covers a 6-24V DC range, which handles most sedan, SUV, RV and truck circuits. The one knock is that the wire can feel like more length than you need on simple jobs.
✅ Pros
- 39-inch PU wire is flexible and lightweight
- Long stainless steel probe pierces insulation
- Bright bulb varies with measured voltage
- Non-slip handle for a secure grip
❌ Cons
- 39-inch wire is more length than basic jobs need
- No body dimensions listed for storage planning

This one wins on storage for me — the 8.47 x 3 x 1.26 inch body slips into a toolbox or glovebox without taking up space. It still gives you a 39-inch wire and a long probe that pierces insulation, and the alligator clip grips chassis components well. The 6-24V DC range covers sedans, SUVs, RVs and trucks like the FEAOXYO. My only gripe is that the smaller body means less handle to hold onto on longer jobs.
✅ Pros
- Compact 8.47 x 3 x 1.26 inch body stores easily
- 39-inch wire with a long insulation-piercing probe
- Reinforced steel and AS construction
- Covers a 6-24V DC test range
❌ Cons
- Smaller body gives less handle to grip
- No non-slip handle listed like the FEAOXYO
Which One Should You Buy?
I think the “best” pick really comes down to how you work — whether you’re crawling under a dash reaching for a flexible wire or tossing a tester in a toolbox for quick checks. Both cover the same 6-24V DC range, so the real deciding factor is the handle and body design.
FEAOXYO Test Light Automotive is right for you if…
- You’re chasing wiring under a dash or in tight engine bays and want the 39-inch PU wire to reach without straining.
- You want a non-slip handle for a firm grip during longer diagnostic sessions.
- You need the long stainless steel probe to pierce insulation on turn signal, headlight or taillight circuits.
Feikenee Test Light Automotive is right for you if…
- You want a tester that stores easily — the 8.47 x 3 x 1.26 inch body fits neatly in a toolbox or glovebox.
- You want a reinforced steel and AS build for a basic 6-24V DC voltage check on fuses and switches.
- You like the idea of keeping a spare tester in the vehicle for quick roadside checks.
❌ Who Should Skip All of These?
If you need to read exact voltage numbers or test CAN bus and digital circuits, a basic bulb tester won’t cut it — you’d be better off with a digital multimeter or a dedicated diagnostic tool. These two are simple continuity and voltage indicators, not precision meters.
For most people doing routine car checks, I’d go with the FEAOXYO for its flexible 39-inch PU wire and non-slip handle. Reach for the Feikenee instead if compact storage is your top priority.
Frequently Asked Questions
Which is better, the FEAOXYO or the Feikenee test light?
I’d give the edge to the FEAOXYO for most people because of its non-slip handle and flexible 39-inch PU wire. The Feikenee matches it on range at 6-24V DC and wire length at 39 inches, but its smaller 8.47 x 3 x 1.26 inch body means less handle to grip. If storage space matters more than grip, the Feikenee is the better call.
Do the FEAOXYO and Feikenee test lights have the same voltage range?
Yes — both cover a 6-24V DC range with a 6-volt minimum and 24-volt maximum. That means either one will handle sedans, SUVs, RVs and trucks on the same circuits. You won’t gain any range by picking one over the other.
Is the FEAOXYO worth choosing over the Feikenee for tight spaces?
For tight spaces, yes. The FEAOXYO’s long stainless steel probe and flexible 39-inch PU wire make it easier to reach behind a dash or into an engine bay. The Feikenee also has a long probe and 39-inch wire, but its compact body gives you less to hold onto when you’re stretching.
Which test light is easier to store, the Feikenee or the FEAOXYO?
The Feikenee wins on storage — its body measures just 8.47 x 3 x 1.26 inches, so it slides into a toolbox or glovebox without fuss. The FEAOXYO doesn’t list body dimensions, so I can’t compare its footprint directly. If you want a tester to keep in the vehicle, the Feikenee is the safer bet.
Are these test lights good for checking fuses and switches?
Both are built for exactly that. Clip the alligator clip to a grounded surface and touch the probe to a terminal, and the handle lights up with brightness varying by voltage. They’re handy for fuses, switches, turn signals, headlights and taillights within the 6-24V DC range.
Can either test light read exact voltage numbers?
No — neither one is a precision meter. They’re bulb-style indicators, so you get a brightness signal that changes with voltage, not a digital readout. If you need exact numbers or to test digital circuits, I’d reach for a multimeter instead.
My Final Verdict
I’m naming the FEAOXYO Test Light Automotive the overall winner because its non-slip handle and flexible 39-inch PU wire make it the more comfortable tool for real diagnostic work. It matches the Feikenee on the 6-24V DC range but gives you a firmer grip and a long stainless steel probe for reaching tight spots. The Feikenee is the better runner-up for anyone who wants a compact 8.47 x 3 x 1.26 inch tester that stores easily in a toolbox or vehicle.
If you’re still on the fence, ask yourself one question: do you reach into tight spaces, or do you mostly want a tester that lives in the glovebox? Tight-space work points to the FEAOXYO’s handle and wire; storage points to the Feikenee’s smaller body.
