Alla Lighting 41mm/42mm 578 211-2 212-2 LED Festoon Bulbs, 6000K Xenon White CAN-Bus Interior Dome, Map, Trunk, Step Courtesy Lights Lamps

I have used the Alla brand for more than two years and so far one of the best aftermarket led manufacturers. I really enjoy having installed this lights on my vehicle. They are bright enough to illuminate the inside of the vehicle and they have a better visibility than the old halogen counterpart. The quality is very high as it's really aluminum and not some old cheap plastic. This translates in better cooling for the leds and this in turn extends the lifetime of the leds, ensuring you will probably just less than three for the lifetime of your vehicle rather than changing bulbs every 6 months like you have to with the old halogens. I'm very delighted and will probably keep odering. Would definely recomend to anyone. Note: depending on vehicles on board computer, there might be an error present on the dash. This naturally occurs because leds use less power than normal halogens and most cars are programmed to once they detect lower power consumption of the bulb they assume that that light bulb is done for. In order to solve the error, either install some resistors on the wiring or better yet get some adapter with built-in resistors that can be removed easily.

Plug and play. Much better lighting option over the bland incandescent.

Love the glow it lights up ur truck nicely

It fits perfectly in my 2023 Challenger R/T and work as advertised. However, they are not as bright as the pictures suggest, so don't expect an overly intense light. Installation was straightforward, but you need to be careful when removing the cover—use plastic tools instead of metal ones to avoid damage. Overall, they’re a decent upgrade for a subtle, stylish red glow

Perfect fit

Best led bulb replacement ever! Will not disappoint. Wonder why I never purchased sooner.

Fantástico

I installed one bulb and it flickers constantly. I like that it's not too bright that I can't see out the windows and it's a good white light. But the flickering is annoying.

This a perfect match for my VW. Easy to install and has not glitched out yet. A perfect remedy for the cargo area light.

Very bright!! I got the blue ones for my gmc and they work great, just push them in and it’s all good to go! Very happy

Works perfect in my Jeep rear cargo area.

If you're looking to make your cab glow look no further. Shipping was fast and the lights went right into my 06 gmc sierra. No flicker and very good colour brightness and depth. Ordered red and was impressed, made the no name brand lights I had installed look terrible in comparison. Sorry for the bad picture quality as my camera is broken.

Never had a problem dealing with this guys with it comes to resolving matters..giving priorities to their customers satisfaction was always first.i’m excited to try another products,and will definitely recommends.
