Have now had owned four of these lamps. None of the lights worked in the longer term. The last still functioning now turns out independently while driving. That is, you go in the dark to be seen in the belief that if one then arrives home one finds the lamp is eventually went back out. A lamp I had complained and sent back. The merchant wrote to me then, the lamp had gotten a quirk and was therefore no longer functional. That is no guarantee. Really great, postage paid itself, lamp completely gone. On the corporate arm, I can myself !. Have times ne 5 Euro lamp possessed that has kept years!
