Just ordered some Osram Nightbreaker bulbs from Amazon (AP Motor Store) £24.56 delivered, and as they are in pairs of H1/H4, means i have a spare set for 'under the seat'. Hopefully they'll help significantly. This is my first road bike in nearly 5 years, and the journey home after picking it up was on a dark wet night, couldnt see a damn thing! Even got passed by an L plater who could obviously see better...
Have done the dual dip mod, got 12v at the dip terminal on the H4 but no light, i suspect that bulb might be no good anyway, but it doesnt look obviously blown on the dip.
