Lights

… but for blinky light city riding, where the beam pattern is not so important as blink frequency and brightness, i love those cheapo alloy torches like the just sold UltratFire WF-5028 or my favourite the UltraFire U4-MCU with a CREE Q5 led at around 15 to 20quid.

I quite like CREE torches too, but please tell me you don't use the strobe mode as a blinking front light in town (or anywhere).

It's a fucking attack/disorientation device. Only any good if you want oncoming vehicles to freak the spazz out and probably lose control and crash headlong into your face.
