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.

The bulbs were an easy replacement within the interior lights in the sound bar of the 2005 Jeep Wrangler. As the photo shows, there’s no comparison with the OEM bulb. These bulbs are much whiter and brighter. They’re a great value and look awesome, while greatly improving cabin lighting.

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

Would r given it a 5 star, but even tho it said that it was the right fit for the use I was seeking, it fit loosely in the prongs that hold it. So I ended up having to squeeze them in with pliers to hold them tighter. Plenty bright bulbs tho

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

Fantástico

These worked well in my 2014 Camry

Well they flicker. I installed these in my work van, which I put about 3-4k miles per year on, so about 1/4 of what "average" drivers do. They have lasted a little over a year before they started to flicker to the point that they were so annoying I had to take them out. Contacted the company and they aren't interested in replacing them. So here is what is confusing. On the product page it states that the bulb life should be 30,000hrs. Ok, 30k hours would be 3.42 YEARS...IF the bulb was on every second of every day. I would estimate that these bulbs have maybe 15-20hrs on them based on how little I use this vehicle. The 30,000hrs lifetime is a total lie. Save yourself the hassle and spend a few extra dollars for a name brand that will back their product.

These bulbs do not allow the interior reading and dome lights (of a 2004 Ram) to function the same as the original incandescent bulbs. They only illuminate when the door is openned (or the vehicle is remotely unlocked). If you want them to function you need to turn the dimmer switch to full on or open the glove box (the bulb in it seems to create the required resistance for them to operate).
