Get Some F**king Lights

I really like the exposure lights which, instead of a normal flashing mode, have a sort of 'pulse' mode where the light is on a low intensity steady setting with bright flashes every 0.5-1 seconds. Seems to solve most of the problems associated with normal flashing modes. They are stupidly expensive though, does anyone know of other lights that do the same thing?

imho they are worth the money. I use that mode on summer evening rides for a bit of visibility on rural roads. It ran the whole summer without needing to be recharged. I get 20+ hours on the lowest steady setting, and the highest setting is incredible and useful on the odd occasions when I just have to have the entire road lit up (heavy rain, tight corner, potholed road, unfamiliar route). In addition I have sold every one after about a year for not much less than I paid for it, and upgraded.
They are tough to buy the first time, but overall I rate them better than anything else on the market.
