--Lebensdauer
In my case (2005 Smart ForTwo) keep the lights just 7.000-15.000km what is decided too little. Therefore the brightness is enormous and is just above the, very good, Philips NightGuide. (The Philips I would recommend frequent travelers, who will stop at frequent lamp replacement)
The price I find OK because the lights are really good. Clear Xenon is a trace brighter but the Night Breaker already make a lot of fun and sometimes you would be even driving in the dark ...
Important: the here several times emerged tip switch only after the engine has started, to pay careful attention !!!
For me, the few ertsten Night Breaker (4 in total) have blown after just 7.000-9.000km. Since I've turned the lights after starting the engine, approximately 15.500km.
