I bought 2 and installed them in a Renault Grand Scenic with a dual function: position lights and brake lights. During the day, when the car's lights are off, they work perfectly as brake lights. At night, when the car's lights are on, their brightness does not change from low to high when someone presses the brake. It remains high all the time. Fortunately, the car also has additional brake lights above the rear window, so the drivers behind can understand when I am braking. I will definitely replace them...

Installation and replacement of rear lights and brake light bulb on Ducati Multistrada 620 resulted in a decrease in power consumption from 21 watts to 3 watts with the LED bulb. Increased brightness in the rear lights compared to the regular bulb and slightly less brightness during braking. This is probably because the regular bulb has a significant difference in brightness compared to the rear lights and braking. Therefore, I give it 4 stars because I don't know about its durability yet. February 2023.

Update: After 6 months of operation, it works perfectly fine.

Purchased for brake light on XR400. Works perfectly.
The incandescent bulb I was using would burn out within 1-2 months.
This one has been working flawlessly for 2 months now and it seems like I won't need to replace it for a long time
