My last GS has a set of Hella FF50's for driving lights, and a set of Motolights for conspicuity. The FF50 lights were great, but no longer available. The motolights were very expensive, and nearly useless. On my new to me GS I want to go with LEDs. I have installed a few different sets on friend's bikes, and have been impressed. BUT, I want to keep the price reasonable, and want driving lights that put out! So, what have you used, pros and cons?
