Sometimes I wonder if a big red “DO NOT TOUCH” just makes it more tempting...
Honestly, I’ve seen the same thing—labels almost act like magnets for some folks. But I’d push back a bit on heat tape being the safer bet. If it’s not installed right or gets buried under insulation, it can overheat. Clamp lights are risky, sure, but at least you can see when they’re on or off. Maybe a locked breaker box is the only real answer, though even then, someone always finds a way...

That’s the truth. I’ve literally watched someone ignore a “Caution: Hot” sign just to see if it was actually hot. Human nature, I guess.
On the heat tape vs. clamp light thing, I get where you’re coming from. Heat tape *can* be safer if it’s installed by the book, but I’ve seen more than a few jobs where someone just wrapped it on and buried it under a mountain of insulation. That’s when things get sketchy—overheating, melted wires, you name it. Clamp lights are old school, but at least you can spot if one’s gone out or if it’s sitting too close to something flammable.
Here’s what’s worked for me over the years:
- If you’re using heat tape, go with the self-regulating kind. It costs more but reduces the risk of overheating, especially if someone piles insulation on top.
- Always check manufacturer instructions—most say to leave a gap between the tape and insulation. Nobody reads those, but it really does matter.
- For clamp lights, I only use them as a last resort. If you do, make sure they’re not touching anything and use a bulb that won’t roast your pipes or start a fire.
- Locked breaker box is solid, but like you said, there’s always that one person who’ll find the key or just flip the main anyway...
One thing I started doing in rentals: I put up a laminated “Winter Plumbing Checklist” right by the panel. Not that everyone reads it, but sometimes it slows folks down enough to think before they start flipping switches or unplugging stuff.
End of the day, nothing’s totally foolproof. Just gotta layer up the safety measures and hope for the best. And yeah, maybe skip the big red signs—they seem to have the opposite effect half the time...
I get what you’re saying about clamp lights, but I’ve actually had more issues with them than heat tape, especially in crawl spaces. One time a bulb cracked from moisture and tripped the breaker—kind of a mess. I’d rather trust properly installed heat tape, even if it’s not perfect. Maybe it’s just what I’m used to, but the idea of an exposed bulb near insulation makes me nervous. Guess it’s a “pick your poison” situation...

Totally get where you’re coming from. I’ve seen clamp lights melt insulation more than once—never a good day. Heat tape’s not perfect, but when it’s installed right, I trust it more too. Sometimes it’s just about what you’ve seen go wrong firsthand, you know?
I hear you on the clamp lights—seen some insulation get scorched myself, and that smell’s not something you forget. Heat tape’s definitely got its quirks, but I’ll take a properly installed tape over a bulb any day, especially if tenants aren’t always careful. One thing I’ve learned: always double-check the manufacturer’s instructions and use a GFCI outlet if you can. It’s not foolproof, but it beats dealing with water damage or worse.
