So if the lamp is out and you get the LAMPF warning it's either the bulb or some problem that impedes the current flow between the bulb and the control module. My first possibility is that there's corrosion or other damage to the socket that plugs in to the bulb. Unscrew the cover behind the bulb and first inspect this. Sometimes the plastic on the plug itself suffers heat damage (maybe from an over wattage bulb) but you're really interested in the metal connectors that join to the tabs on the bulb. The connectors can also loosen over time and a little work with a needle nose pliers can tighten them up. An easy field cleaning approach is just to remove and reseat the plug several times and see if that fixes it. If that does the trick go back and add some Deoxit from Radio Shack. It's not hard to find replacement plugs that can be spliced in there.
Note that the bike keeps the lamp off until the engine is running, so an effective intervention won't be apparent until after you start the thing!
Bulb filaments can sometimes break and then fuse themselves back together temporarily, so check the bulb either visually (if you see a break in the filament it's toast) or with an ohmeter (should have nearly zero resistance if good, infinite if bad) or just by swapping it out.
Similar thinking if you have an HID conversion, but there's more stuff to understand between the plug and the element. Either way, if the current flow across the circuit isn't right you'll get the warning. A short might do the same thing, but I'm not sure of that.
hope that gets you started.
