Botepon 4Pcs 211-2 212-2 578 LED Festoon Bulb 42mm 5050 3SMD Canbus Error For Car interior Dome/Map/Trunk/License Plate Light Blue

The media could not be loaded.  VEHICLE APPLICATION: 2018 FORD F-150 exterior bed/cargo lights, mild climate, vehicle nightly garagedUSE TIMEFRAME: May 2018, began failing Jan/Feb 2019, approx 8K miles on-vehicle use, illuminated nearly exclusively for brief entry/exit and not extended cargo loading illuminationPOSITIVES: As others mentioned fantastic lumen brightness and all LEDs worked right out of box. Very reasonable price. No "code" of faults thrown due to decreased power load.NEGATIVES: Short-life (see timeframe) as they fail light began to flicker and dim as each individual LED begins to fail. Failure not power related... occurs when vehicle is and isn't running. Failure first began in winter months with coldest outside temps (lows 20F-35F) but failure continued to get worse even AFTER weather spring temps rose to 60F+.OVERALL: I'd proceed with caution. Maybe I got a bad batch - or they just performed poorly in my specific vehicle application but even at a affordable price you still have to consider the cost of YOUR time to frequently install and replace these bulbs. Light illumination (when working) is GREAT, but when they begin to fail its embarassing and not very useful. Item description states 12mo warranty - these failed within 10mo of use, but I am 2 weeks over the 12mo anniversary of my order date... I will contact company to see if they will stand behind the product... IF SO I will note the level of customer service I receive.

Was going to give four stars...due to brightness but because it's sold in the same listing as other colors I don't want to bring the rating down.Ordered the red 211 set. Not as bright as I wanted. But sturdy and looks very well made. Has a mini heat sink on the back. Using as accent lighting in my 2011 international ProStar. 4.5 stars really.

Yes, they are very bright. I was very happy for a few months. I used these to replace the original dim bed cargo lamps on my 2020 Ram 1500. The lamps come on for 1 minute whenever you open any door. They were fantastic. After a few months, one started to flicker, I thought it was an unusual failure. I ordered a second set as a backup. Within a few weeks after the first failure, the second lamp started flickering. Darn.I finally got tired of both bulbs flickering. So, I just installed the backup set. Less than 6 months of usable life is way too short for a bulb that is seldom on. They would get 5 stars if they didn't both fail. I really like the brightness.Update: I have now updated the vendor/product from 1 star to 5. Right after submitting the original review, I contacted the vendor, and they got back to me within hours. They apologized, and shipped a new set of lamps as a replacement. That says a lot about their commitment and customer service. Let's se how long these last.

I replaced the Backup Light on my 2017 Lexus ES 300h. The Botepon LED replacement was truly plug&play and performed well. The LED is nice and bright and well made. However brightness also depends on the design of the vehicle's reflector housing too. In my case, the Lexus reflector could be better, but the LED bulb performed well. After receipt and inspection, I like the Botepon LED because the circuit board is nice and thick with nice electrical contact area. Workmanship is clean and the LED's are nice and big. Installation Tips: After insertion of the LED into the socket, you might find it slightly loose even though the LED circuit board is thick. This shows you how much play there is in the socket. How to fix? I used a small screwdriver to bend the clips in the socket closer together. This method held the LED bulb nice and tight. The LED's lit after the first insertion. No need to flip for polarity. Be sure to test LED's before replacing any inside body panels. Now at night I can see much better when I reverse. Enjoy!!

I needed Canbus LED lights for my 2015 RAM 1500 because one of the LED lights installed in the bed light by the previous owner was flickering, and the non-LED light he left in the third brake light (not sure why he did that, other than to keep the system from complaining about the brake lights being burnt out as can happen with non CANBUS LEDs, which he had put in the bed lights) had burnt out.They have only been in the truck today, so longevity may be an issue (although the manufacturer says they have a 50,000 hour lifespan) that remains to be seen.However they are AMAZINGLY bright. Now I can actually SEE inside the bed at night!Also, they cleared up the error (bulb out) being reported by the actually burned out incandescent third brake light bulb, and didn't throw it when replaced by the new LED bus as non-CANBUS LED bulbs so often do.I'm very happy with the purchase so far!!

Several months ago I purchased some white bulbs similar to these and I purchased this brand for red lights in the same marine dome light. The red bulbs were really bright and flicker-free. The white bulbs from another brand were flickering and it was annoying. I ordered the Botepon bulbs in white to replace them and so far I am very happy with them. There was zero flicker and they are brighter than the bulbs they replaced. I am ordering a few more for other locations and spares.

Brilliantly bright bulbs but unfortunately I did not read the specifics that explain that these bulbs should only be used as replacement back-up lights. I had been using the bulb as a replacement for the high mount stop light because on a 1998 Corolla, such as mine, both the back-up light and the high mount stop light are the same bulb: #921. Needless to say, the return period that Amazon offers had long passed. I then reached out to Botepon directly and explained the situation and they so graciously said that they would refund the full amount of the bulbs. Awesome customer service! Thank you!

A little bit longer in length than your typical interior bulb, but the brightness and colour was spot on.

Very bad quality, one was tilted after two weeks only
