Best Industrial Electrical Indicator Lights of 2025

"I got these to replace my older LEDs that were failing as indicator lights."

"I had to deduct one star since the wires' polarity wasn't marked. It's important to identify the positive and negative."

"I purchased these for my boat's electrical panel. They fit perfectly and offer great value!"

"These worked well for my application, but I initially thought the 6mm measurement referred to the diameter, not length. They're quite small!"

"This little LED light exceeded my expectations. It did exactly what I needed it to do and was a great deal."

"I installed one inline with a light switch at church. It's a great reminder for me that the Church cross light is on and should be turned off at the end of service. The only thing is they don't turn off instantly but slowly fade, which doesn't affect performance."

"I really liked that what I ordered was exactly what I received, so I’m giving it a 5-star rating!"

"I absolutely love these lights and have purchased many. I wish I could give more than 3 stars, but I find the terminal connectors to be quite loose in every one I've bought, which concerns me. Nobody wants a wire to come loose and cause issues. The wire from the light to the terminal connection is also very thin and fragile. I would gladly buy these lights again and give a 5-star review if those issues were resolved."

"I used this in my shop to check if the compressor was left on. It works great and is nice and bright."

"My husband got these lights for our garage door. We initially thought they would be too small, but they are perfect!"

"I’m rewiring an old tractor and wanted an oil pressure light. This was easy to install and is visible even in sunlight. I plan to use the extras for future projects."

"I found the product to be good value for the price but not as bright as I expected in this age of 'very bright' LED lamps."

"The lifespan was decent, lasting just a bit longer than it took to install, which was a pleasant surprise for me."

"I noticed the blue LED was working intermittently, but overall, I think the product is worth the money."

"I ended up ordering a second set since one of the lights failed within 5 minutes of installation, but it was easier than going through warranty."

“I had a small strip in my truck that lacked light. These LEDs provide the perfect brightness without getting hot at all. They were super easy to install, and I'm thrilled with the results.”

“After 34 years, my Whirlpool trash compactor light burnt out. I ordered these LEDs for a quick fix. I just slightly enlarged the original hole and connected the wires. They work perfectly in either orientation, which is a plus.”

“I bought these for my classic car as indicator lights for my line locks. They fit perfectly in a 1/4" hole and are nice and bright for their size. I am very satisfied and would highly recommend them.”

"I love the variety of colored 24V LEDs. The easy LED replacement feature was a big plus for my setup!"

"I was a bit disappointed with the flimsy wires and had to resolder them, which was unexpected."

"These worked perfectly for my 120V electronic project, but I just wish the quality was a bit better."

"I struggled to find nice looking turn signal indicators for my golf cart and was excited to find this kit. After installing them in my EZGO RXV dash, they look perfect. While I don't plan to use the headlight and brake light LEDs, the kit was still worth it for me. The first order had a cold solder, causing the wire and resistor to fall off, but I returned it for a replacement. The output is uniform, not too bright or dim, but the lenses trap dirt in the grooves, which is noticeable when lit. Overall, I'm happy with how it turned out!"

"I really like the fit and finish of these indicators, and the colors light up nicely. The installation was easy for my custom dash in an old Jeep."

"Using these on my side by side was a breeze; they fit well in small spaces and are quite effective."

“I had to replace the thermostat in my deep freeze. The light is much brighter than the original, and it was easy to install since the 8mm fit perfectly in the existing hole. I would definitely recommend it!”

“I purchased this set of 8 LEDs to create a night light for my room's light switch. For just $10, I got two each of Red, Blue, Green, and White LEDs, complete with mounting nuts and gaskets. The LEDs are ready to use right out of the package, and I appreciated that they don't require worry about polarity. However, I found the blue LED too bright for my needs, so I simply dimmed it with painter's tape. At about $1.25 each, these LEDs are a fantastic deal.”

“I used these lights to indicate when my central heating is on. They required no additional resistors and worked perfectly for my application. The item looks and feels good, and when hooked up to a battery, they function well.”

"I bought this indicator light for a switch panel I designed to power an electric fence charger at my chicken coop. It clearly indicates when the fence charger switch is 'ON,' which is great for my kids and chicken sitters. We can see it glowing at night from about 175 feet away, making it easy to know if the fence is armed. Very pleased with this product."

"Initially, I was concerned that a light rated for 110V and 220V would be too dim on 110V. However, it glowed just fine on 110V, which was a relief."

"I installed this light in an electrical enclosure for a kill switch for my shop. The installation was straightforward, with easy-to-use terminals. I ended up with an extra one, but the price for two was less than buying one."

“I found that the 12V bulbs are too bright, but at 5V they work perfectly for my indoor projects.”

“These lights are a fantastic value! My only issue is that the screw terminal plates can turn, making the wire connection less secure, especially with 14-gauge stranded wire.”

“I needed an on and off indicator for my water level controller, and these lights fit the bill. They are a bit dim in direct sunlight, but work great in the shade or at night.”
