Ok, so let's talk business. Could I upgrade the light below, which is currently an incandescent? I'm a decent bike mechanic, but no kind of electrician. I have soldered in my life, but beyond that, I don't know much. I'd rather try myself out on this, not caring much if I botch it, than on my EL500, which is currently fairly useful, and cost £40. Is it possible? Warning: should the answer be yes, more questions, and probably a whole thread will ensue.
