I have installed the LED indicators on my motorcycle, to mount the lights was not a problem. Only the resistors had I ordered were quite complicated to build in, as they should be in the vicinity of the indicators and should be installed on the frame of the motorcycle (because of the heat) ... anyway ... here it comes now to the LED Blinker. They have a good brightness at night and during the day. The look had at first convinced me and after I was mounting over the moon! The simple look only class and for the money I can only recommend. So far, they have since 2 months with me in use and function properly. The only thing that bothered me was that I did not find any technical data on the indicators on Amazon ... for a star deduction. Here the data the indicator if jmd still needed: Operating voltage: 12V Power: 1.5W
