Excellent, replaced my existing bulbs with these and they are great

So my old led bulbs needed replacing in the car.. some failed, now they were bright. I was impressed with the old ones and didn't think i could get brighter.Now aliens from space can see me open my car door. So bright I love them.

They work well and have brighten up a landrover

On time delivery with prime membership,Does exactly what it says on the packaging. a much brighter alternative to the yellow hallogen standard "Stock" fitted vanity lights within the sunvisor.No trouble at all and I expect these lights to last longer.

Very bright 😊 bend slightly when putting them in, lil fragile in that sense l, but once in, great bright white pure light 🤘

No Canubus issues thus far. Good light

Easy fit, nice bright white led, 20 pack was a bargain. Would recommend.

Terrible they’re not 28mm as described

The original interior light bulbs were dim, making it hard to see inside the van. With these bulbs, the interior of the van is as bright as daylight. The diameter of these is slightly smaller than the originals, so I had to bend the metal holding tabs together just a bit to give these bulbs a snug fit.

I installed 2 of these in the front "dome" lamp position in a 2014 Chevy Tahoe SSV. This was not so much for more light, as the vehicle has 2x 212-2 incandescent bulbs in each of the (count 'em!) SIX dome light positions (2x front, 2x mid, 2x rear), plus a separately switched aftermarket warm white or red dome light in back of the front two factory lights. However, the 6x 212-2 bulbs do draw significant current, and modern starting batteries don't like that a lot. I measured one of these well used** 212-2 bulbs as drawing 0.74 amps at 12.8 battery volts = 9.47 watts. Six of them would be almost 6 amps. I guesstimate new bulbs would draw at least 6 amps. That's not "awful", but in a situation where the vehicle may be sitting turned off yet with a good amount of the lights usage...Replacing the 212-2's up front gave me a TON of good quality warm white light. It's a little less yellow-orange than the 212-2's, esp. with the engine off, so I'd say a 3000K rating is just about right, and with a nice spectrum overall. It's almost as good as a name brand indoor / 120v AC warm white bulb, IMO. Map reading is much easier, which is great for my gettin' old eyes! The disadvantage is that now there is much too much light to have even the passenger side on while driving at night. There's no manual dimmer function for the dome lights, so if I'm driving and wifey needs to get to something (or vice versa), then the aftermarket light is further back and less bright. :-)Fade out of the LED lights cuts off a little more abruptly at the end of the fade, than do the 212-2's, but it's not a problem. I've noticed no problems with flickering, etc.That all said, I may well try out some even lower current LED bulbs here -- I see some on Amazon rated at about 1/2 the lumens and just 0.9 watts which would be only 0.07 amps. If those behave, I may put one of the lesser bulbs in the passenger front position and two in the middle dome lights, leaving the stronger bulbs over the driver and over the cargo compartment.These bulbs may have some good possibilities for emergency lights that take 211-2 or 212-2 bulbs, also, IF line voltage cutoff or turn on spikes making it through the power supply are not a problem. (I'm thinking "not", as good quality home LED bulbs seem reasonably resistant to "everyday" line voltage variations. However, check with the manufacturer...)

These are great LED lights for your vehicle. They upgrade your interior dome lights by projecting a cool, white light as opposed to the older orange style.They are easy to install and work well! I highly recommend them to anyone… just make sure you check the bulb pattern in your car before purchasing.

It worked as described

This is really a great quality product. I started with 300 lumens, dropped to 100 lumens, and then these are 50 lumens. This is still too bright for my liking. I have found that 20 - 25 lumens for a vanity visor application is best. Still looking, but these will do until then. I would consider these to be the maximum brightness for vanity / visor.
