HELLA 921LED 5K LED Performance Bulbs, 12V, 1W 2 Pack

These LEDs are amazing! They make the interior of my Mercedes SUV look very classy compared to the OEM incandescent bulbs, especially with these being a nice 5000K Natural White VS the typical “harsh” 6000K cool white replacements. Yes, they aren’t as bright as other LED bulbs out there, but they are plenty bright for use as interior lighting. I previously had some really good 6000K bulbs in my interior, but nowadays I can’t seem to stand the cooler color temperature especially in the cabin of the vehicle - makes it feel like you’re sitting in a laboratory of some sorts. While the 6000K I previously had installed were much brighter (TOO bright to the point where you’d get blinded/headaches at night when you’d shut the vehicle off or open the doors), these new Hella 5K LEDs are what I’d consider to be an appropriate level of brightness/warmth for interior lighting, I’d say they’re a step up in brightness from the OEM 6 watt incandescent bulbs that were originally installed in here. Overall, I’d highly recommend these bulbs if you’re after a nice natural white 5000K appearance vs the super common cool white of the 6000K. I’ll update this review as time goes on regarding the bulbs durability and lifespan.

Worked great, and improved visibility. I got them for my ‘88 260E Mercedes-Benz. Easily installed in cluster. Pretty budget friendly. They are bright enough but not too bright. May be too bright for purists tho. 1st pic is during the day, 2nd is at night.

Used these in a boat stern light. Way brighter than old stock bulb and a more white light. Can't attest for longevity but they're from Hella so I don't anticipate any problems

I bought these as my car says it takes a 921 for the reverse lights. However, the reverse light is about double the size. I installed them in my interior hatch instead. they are brighter than the stock lighting. But they aren't bright enough to fit my 2013 Acura MDX as backup lights. Need to go pester Autozone to see if I can find the right size bulb for the backup lights.

If you have problems where you want to change your lights for LED lights, but when installing the new ones the light stay dim and won't turn off, look no further, these are the ones you are looking for! I tried, Sylvania and Philips, both would stay dimm and won't turn off.

I was looking for something good to for my semi truck sleeper ceiling light. Originally had halogen bulbs but they drain too much power from battery and get hot and they are yellow color. Decided to give these try but they not as bright as I thought they would be. I'm still in search for brighter ones with the same socket size. Although these could be used for different purpose

Replaced the old lamps in my exterior dome light and break light on back of cab with these. They fit perfectly and work fine but I don't think they are quiet as bright as the original lamps. That said, I'd buy these again if I had to replace them again but hopefully they'll outlast the truck.

Wanted to test these out before replacing the dome lights to make sure it wasn't too much, so I used these to replace the courtesy/step lights on a 2002 Highlander, they were all very dim. Quick and easy fit, no flickering and way, way brighter. Picture shows the tone of the interior lights vs the new LED in the doors. Will definitely be upgrading the dome and map lights now!

Pessoal, para quem não quer uma luz azulada, esse é show.... Branco conforme desejado. Possui 5000k de temperatura conforme a tabela, quase que devolvi por causa da imagem que mostrava que era de 5000k, porém tinha um leve amarelado, mais fui na teoria da tabela e é branco, não tem amarelado e nem azul, vai ficar perfeita com minhas limpadas de temperatura de 4200K. Nota 10, lampadas super e bem acabada, Hella tem enorme qualidade em seus produtos vale a pena

Perfect colour match for HID without being too bright. As my intended use was to replace the parker lights, you don't want these to be bright, hence these Hella LED suited the purpose well. Those who are seeking brighter LED's for interior dome lights, may want to try Philips or Osram.

EXCELLENT

¡Muy bonitos! Son exactamente lo que buscaba. Muy pocas marcas tienen la tonalidad de 5000°k, que para mí es la más bonita. No como los LED's genéricos que después de un tiempo se ven casi azul o las tonalidades de 6500°k hacia arriba, que de igual manera, son un blanco azulado que no iluminan tan bien y a mi parecer no lucen. Yo lo único que buscaba era la tonalidad, un color armónico y bastante elegante, pero me también me sorprendió la cantidad de iluminación. He comprado muchas otras marcas durante años, pero estos ya se volvieron mis favoritos. En las imágenes que anexo, el vehículo utiliza solamente un foco de pellizco o T10 o 921 (según como se le conozca) y esa es la calidad de la iluminación.
