High Output 12/28VDC BA9S T3-1/4 Miniature Bayonet Base LED Replacement Bulb | Replaces Bulbs 12V: 1414 1416 1813 1816 1895 | 28V: 313 1495 1819 1820 1864 757 (2-Pack; Bright White) (2-Pack; Red)

The product quality is top notch. It is very bright as you could see in the picture neon bluish, greenish color. The light bulb color was white. Am a trucker who mostly drive at night and turns on lights at any given time. I do recommend them.

I saw this same light on a German website that described it as fitting my Pfaff. They did not ship to the US. This one appears identical. It fits my Pfaff Tiptronic 2040 sewing machine. This is a super bright light. The two LEDs on the bottom of the bulb are the key. The original halogen was SO hot. This is cool and brighter. It is also on the cool light spectrum. But for me that's OK since I want to see color variations properly when sewing. If your sewing machine shares the Mini bayonet / Ba9 / Ba9s size with the Pfaff 2040 ( a lot do and there is a list of machines that do on some sewing websites ) then it should work. I needed 12 V neutral polarity and this says 10-30 V. Neutral polarity. In addition to the two LEDs on the bottom it has three LEDs on the side of the bulb. I am happy. Will update later.

Lights work great. Were bright.

Our classic 66 Mustang needed better illumination on the stock dash cluster. Shopped around and found these. Wasn’t sure they would work on a vintage set upThese LEDs sure did the job. Love the lightingThe older classics didn’t have the brightest lights, but these workThe blue really looks nice

Brand new, right out of bag, one bulb didn't work. That's a 10% failure rate

Expensive but I’d buy them again. 👍🏼

Update #2: Received the replacement bulbs very fast from Amazon and used them on a different Circuit 12 volts DC on my Video Camera power supply and 24 hours of being ON are working great and just as bright as the 28 volt and no burning smell! Not sure why these won't work with 28 volts that worked with 1819 bulbs that YES it was an AC 28 volts but has a rectifier changing it to DC 28 volts! Most people are going to buy these for Automotive and these are Awesome for that if they last! Very Very Nice Quality Bulbs and the color and brightness is almost Laser brilliance! My camera can't even capture the illumination! I added another Star to this product and if it lasts being that bright more than a year I will be so surprised and give it 10 STARS! so I might buy more of these if they are still working next month?Update: These Might be great for 12 volts but not to replace a 1819 bulb on 28 volt power supply! The Bulb that worked of the 2 bulbs, I left it plugged into the 28 volts and later I could smell it burning in my basement so I am returning both bulbs, So I have no idea how these work or what it will replace but it will not replace an 1819 standard bulb connected to a 28 volt power supply, the 1819 bulbs lasted about 30 years or more but I wish these worked because they are really nice color and bright when they work!(Original review) ; One of (2) bulbs DIM / Defective the other one is Super Blue Like the Working Bulb but the other one is just glowing so not sure how long the working one will last being one defective right out of the package, My regular 1819 bulbs last about 25 years on my Zone Valves on my heating system, These LEDs are beautiful color and Super Bright! One Review says that their Bulb burned out within a few days so I'm Skeptical or I would order more and of other colors like green. So Glad I don't have to do much to install these like as if in a dashboard so I am returning the defective bulb for a replacement and see how that goes.

Great so far, maybe 1 hour of night time use. I put them in my M35A2, supper bright.
