5pcs 8mm LED Metal Indicator Light AC/DC 12-24V Waterproof Signal Lamp Pilot Dash Directional with Wire

Are you HOT? (Or NOT?) Subjet: Electric water heater operation/monitoring.Begin here: I now live solo. I retired my 55 gallon LP water heater. And using it as room temperature reservoir ahead of a 20 gallon 110V electric water heater. Big $ saver right there. 20 gallons is plenty for a shower or dish washing once a day. But why stop there? The “reservoir” and water heater are located in my basement. Keep reading.The 20 gallon water heater is on a timer- ON 6am- Off at 10 am. How do I know , in the morning, if the water is hot (timer working?) Water hot?I installed 4 of these LED Indicators. Two upstairs, and two on the water heater. One pair indicates the heater is ON (direct from the power/timer to the water heater). The other pair tapped to the heating element in the heater.I can see at a glance: One LED ON= Heater is “on line”= water hot. Both LEDS on= Water is heating. When #2 goes off? I have hot water and good to go!If I I need extra hot water? I have a switch upstairs that bypasses the WH heater timer.Simple circuit(s). You don’t need a degree in electrical engineering to pull this off.I have calculated this “on demand/as needed” water heating costs me $5.00/month for hot water in the. Morning or as needed afternoons/evenings (rarely). Compared o keeping hot water available 24/7 that I don’t need or use.Sum total of this: Monitor hot water needs and usage. Save big $ on your gas or power bills.What I meant to say was: The old school neon bulb 110V indicators last a about a year…. Then burned out dead. Lets see how these hold up?Have a nice day!

No used it

Great product

They worked . Had one bad one , but only needed 4 . Could be brighter but I'm happy

As you can see, I installed this on the switch to a remotely located air compressor that runs on 240 v 3 wire. Not being an electrician but having wired my shop from panel to panel and inside and passing inspections, I felt like this should go easy. I had to rely on information from DIY Community to figure out how to wire this as the instructions are for 12v. If you are installing this as I did, wire both leads (I had to add pigtails so I had enough line to work with since the light was fastened to the cover) but both leads go to the load side of the switch. The light is a darker red than the picture shows. Very pleased with the outcome, wish the instructions were more concise.

I plan to use these as indicator lights to show me when my well pump has switched on to detect for a situation where my well pump is continuously cycling off and on in the case where the check valve in the pump has failed.Fortunately I caught it the last time the check valve failed, just by luck, and it saved me having to replace a $500 well pump before it burned out.I just had to replace the check valve (about$30).

Used to replace burnt out indicator lamps on old electric stove , they look great!

Added light to my pool pump timer so I can tell if the GFI receptacle it's attached to has tripped or not.
