Review on Botepon LED Festoon Bulb Set For Car Interior: 211-2 212-2 578 Bulbs, 42Mm 5050 3SMD, Canbus Error Free, Blue Light by James Baker

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!
