Shall we put "meters with built-in flashlight" in the same category as "meters with transistor tester",  ie. guaranteed to be junk?

Yes
No
How will I solder SMD parts without my flashlight?
Don't you know it's dangerous to work with electricity while holding a flashlight with your teeth!
It's spelled "torch", but yes.

Let's put this important question to bed once and for all.

How about with a built in soldering iron?

Only if both probes could heat up so I can solder both ends of a component at once.

Probably less crazy than one with a Bluetooth speaker:

Anybody have tales of people who lost their front teeth during an electrically-induced spasm?

Here's one:

And is completeluy useless as a flashlight... As multimeter, is above Aneng, but way below Fluke(year-on-year stability).

I have a Mastech 2108 which has a "flashlight" bloody colonials for the jaws, and I can tell you it's bloody useful; when you're reaching in the bottom of an old panel board with those 400V tails bolted onto busbars, I REALLY want to see where I'm putting my hand, tyvm!

DMM leads with built in lighting would be far more useful.

No one heard of headlamps ?  :-//

You can sort of get that with some DMM's:

I have some probe clip-on's in a draw somewhere with a LED (I think they are Fluke branded). Don't remember why I bought and I don't remember every having used them. I think they came with a probe set I bought for one reason or another.

I picked this up one day in a fit of madness:

https://www.keysight.com/us/en/product/U1176A/led-probe-clip-light.html

It "works" if your workbench is a dimly lit dive bar, but otherwise it's laughably bad.  It comes apart easily enough, so I have plans for an upgrade at some point...

Some light at the meter is not that bad. At least it can be made in a safe way. The cheap LEDs are isolating be default. Transistor test function usually comes with compromised safety - otherwise the function is not that bad.

However for direct use while measuring the light at the meter itself is usually at the wrong place. Today most cell phones provide a light too, so the exrta light is no longer that much needed.

Probes with light may be a nice idea, at least in come cases for more fine electronics.

Yep. You can hold s phone on the back of the meter and get a much brighter light.

Not that bad idea actually 8)  Even industrly heavyweights have "torch for your DMM" solutions:

The light in the clamp jaws of my Mastech 2108 is in exactly the right place, and means I don't need an extra hand for a phone or anything else, as my other hand will be keeping me from falling head first into the pit under the panel board in the LV side of the substation.



I also have some probes with a light on the red one. I think it looks like the hunter-seeker from David Lynch's 1984 Dune film...

These days there are tons of great LED headlamps and flashlights with magnets/clips.  So if I'm doing real work I have no use for anything less.

I didn't vote because none of the choice fit my thought. I do not think such a meter is junk but I don't want it because flash light eats battery a lot and I don't want to change battery in my meter often.

Normally sparks fly when I use a meter so I don't need the built-in light.  :-DD

My Fluke 771 Milliamp Process Clamp Meter has a tiny white LED built in, but to be honest if you can benefit from that tiny amount of illumination to see what you are doing you should probably not be working in the cabinet.

I also have some probes with a light on the red one.

I always wanted something like that for continuity testing , ie. the probe lights up when there's continuity.

Yes well, sometimes you just have to get the job done. Very carefully.
