Hello, immediately after the purchase of my XYR 1200 in 1998 I installed a half-shell, which was manufactured in Italy and distributed via Yamaha. Meanwhile the luminosity of the Ablelllichte is no longer sufficient. On the bulb and the power supply it is most likely not. The headlight is from tri.o.m and has the number 400032-1-2. Has someone had the same problem one time? Can it lie on the reflector or the optics for the dipped-beam? Does someone know where I can buy a new headlight cheaply? Thank you and greeting, Bernhard.
