I have a 4 year old Deluxe 28 and need to replace the light bulb. I looked on-line a found it was close to $10 for just the bulb. I'd consider replacing it with an LED. Is there an LED that will fit in the socket? If not, is there an LED assy. that can be mounted? I've seen the threads on creating your own. Rather not have Mr. Goldberg hanging on my handlebars.
