Alopee DE3175 Led Bulb Warm White 3000K 1.22 inch 31mm Festoon Led Bulb Non-Polarity Error Free Replacement for Dome Light Map Door Trunk License Plate Light, Pack of 6, DC 9-28V

I installed 2 of these in the front "dome" lamp positions 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 4.5 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, such as at a camping spot... 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., but, again, the dimming function in this SSV version of the Tahoe has been defeated. 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...) Update: 10/5/2024 -- These bulbs have been in the Tahoe for almost a year now, with no problems noted. The brightness without the harshness of lights in the 5000k and up range is much appreciated. These are probably brighter than need be for the 2nd row seats (middle dome lights), but, until I add something else in the rear for camping uses, the work pretty well in the rear dome light positions too - the only issue being that they do draw more current than some lower lumen lamps, so you don't want to forget and leave them switched manually "on". I did edit my original review slightly for clarity and accuracy, tonight, but, none of those impressions have changed significantly. Overall, this is a good product. It is not "the cheapest", but the price is reasonable for the performance. I'd like to see the seller offer a 10 or 12 pack, or some other quantity discount. :-)

These are essentially the exact same size as a traditional 6411 incandesent bulb. These fit my old dome lamp housing perfectly. The light output is much brighter than the old regular lamp, and this uses 1/5 the power: 2 watts compared to 10 watts for the old one. This runs a lot cooler. The color is advertised as "Warm White" 3000K and I believe this is correct. The light color is not strong amber, but it's not harsh white either. It's a soft amber; very pleasing. The only other question is: Will this last?

bright! color is warm and not harsh, good for automobile dome lights and RV fridges!

These bulbs aren’t blindingly bright like other bulbs. They have increased brightness over a regular bulbs with a pleasing warm color.

I absolutely love having a brighter dome light in my car. The old incandesents were awful and I could barely see anything. These looked a little more yellow than I would have liked but the brightness more than makes up for it. As for longevity i cannot comment on the yet as ive old used then for 2 weeks so far

The ends were too small - not a replacement for the #578 bulbs that are in my vehicle.

Nice and much brighter than original bulbs. Now I’m kicking myself for not getting these sooner. I can really see stuff in the trunk too. These are the nice pleasing 3000k color, not the harsh white like other LED bulbs.

I’ve tried several different brands/specs and these are by far the best. Polarity agnostic, really bright, and a pleasant warm color temp.
