I just installed these and I am very happy with them! I can't speak to their longevity because I've had them in for about 10 minutes, but I'm very pleased with everything else.I needed a bulb that matched my three requirements: color temperature (3000K), very bright, and most importantly needed to work with car's electronics. I actually tried several other bulbs before, but I could never get a bulb that worked within my requirements. I don't understand how it works, but some bulbs messed with my car's key fob. Maybe it was some signal interference, but I don't know. I heard that some cars require CAN bus bulbs (controller area network bus).I don't know if these are CAN bus bulbs, but they work in a system that requires them. Plus these bulbs were actually the right color temperature, not that super white color that everyone sells. And they are super bright!

Many LED bulbs have a very bluish-white color to the light. These give off a very warm light similar to incandescent.

I have a mid-90s car that I wanted to put LEDs in, but I didn't want that modern, blue-tinted LED light look. These LEDs do a great job matching the old, warm incandescent bulbs. These are definitely brighter than the stock 194 bulbs they replaced in the map lights, but not so much that it's painful to use at night. But they use so much less power. Really good upgrade if you want to keep the classic incandescent look.

These T-3+1/4 wedge base LED lamps have brightened my car. The original #192 incandescent lamps had left the map lights dim and directional: useful, but requiring special positioning of documents "where the light was" for good viewing. These LED lamps provide both brightness and spread (flood), rendering everything in my car's forward cabin well lit. Just one of these outperforms even the car's dome light, and two of these simply put the dome light TO SHAME.The color is simply white: neither the tan of "soft white" nor the sometimes blue of "cool white" or "daylight". That suits me well, as I dislike either extreme.These are dimmable, though they behave a bit differently than incandescents. These get rather dim by about 9 V and drop out at about 7.5 V. A #192 incandescent, on the other had, still shines somewhat at 7.5 V. In my car, the difference seems minor to moderate: these dim noticeably and then extinguish from a somewhat brighter level than the incandescents.Conveniently, the "nonpolarized" claim is true. Plug the LED lamp in any way you like. If it fits and you've got a 12 V electrical system, it works.Some hints are required.CAUTION: Do NOT use these for side marker, license plate, nor similar exterior lighting unless you can determine the result is similar to your vehicle's original incandescent lamps. Why not? Federal motor vehicle regulations. U.S. Code of Federal Regulations (CFR) Title 49 ss571.108 (overly intricately Title 49, Subtitle B, Chapter V, Part 571, Subpart B, ss571.108) specifies lighting intensities, to promote safety. Sure, you likely won't get a ticket, but go ahead and do the right thing.While these have a T-1+3/4 (OK, T10 metric) wedge base, they exceed the overall size of T-1+3/4 lamp and so simply will not fit in some applications. So, check for space. The body reaches 15/32" wide (about 12 mm) and the total length is 1+3/32" (about 28 mm) with a "bulb portion" length of 0.8" (about 20.5 mm).Contact issues may prove easily resolvable. Just bend each wire so it runs diagonally from right next to the center ridge out to the edge of the base. That's it! One of my car's map light "sockets" (not: just pairs of folded sheet metal contraptions with each pair intended to somehow have its contacts remain parallel) gave contact trouble even with the original incandescent lamp (cured by depriving the "socket" of power and judiciously applying needle-nose pliers). Both "sockets" eventually gave contact trouble with these LED lamps, _until_ I reshaped the LED lamps' contact wires as described above. Presto! Reliable contact and uninterrupted luminous convenience.

These use a higher quality LED than other cheap options. I bought a couple of different types to test out and these were the brightest even though they used less LEDs. Color temperature is good as well, definitely a soft white, it was about the same color as the incandescent it replaced. In the pictures one shot shows this LED vs a cheaper and larger LED and the other shows this LED vs the incandescent. The dimmest was the incandescent, then cheap LED and the Alopee LED was the brightest. Test was done with map lights of a Rav4.

Bought for our golf cart. They worked very well, just make sure you line up the prongs correctly.

brightness and light quality are good but i broke 2 of 4 just trying to get them in and out of the socket and into the lens fixture. it's a tight fit into the fixture because the bulb end is so much bigger than a standard 194 bulb. i also had to add solder to the connection wires on the bulbs because the part that plugs into the socket is thinner and has only 1 thin contact wire whereas the old 194's had a looped wire effectively giving you double the contact area.

For DIY’ers: Base can be trimmed on both sides with sharp blade to achieve stock height (where bulbous shoulders of base make contact with socket), if water intrusion is not an issue
