These mini stalk lights from K+S are worth the value. They are a simple way to change the look of your bike and are easy to install. They only place you can run into trouble is if you need these lights to be on as running lights. These are only single filament bulbs. In order to make them work as running / turn signals; you will need to either purchase a special "Blinker" module or be very handy with diodes and wiring. Its worth it though to give my bike a cleaned up look.
these do the job. look good on my black bike and are brighter than i expected with the smoke lens. i put two on the front and will probably put two more on the back. not flexible and will break easily.
The look and fit are very good, but... I've had these (two sets) installed for less than two weeks and within one days use had a bulb SMOKE! I was sent a replacement bulb for it (right rear). Now upon my third day of use another bulb has burned out (left front). I would not recommend these due to cheaply produced bulbs that you can not get except from DK.
