My CBR 600f4i tail lights not working brake lights head lights everything else working no tail lights pls help ???

I had the same problem, what I did to fix it was as follows:

• Removed the plastic light holders from the tail lamp.
• On each of the three bulbs there is a ground wire that is attached to the plastic light holder via a screw. Remove these connections and clean, I used some very light sand paper.
• Reassemble, Worked like a Charm for me, and I save a $90 charge from Firestone by doing it myself...

SOURCE: Tail Light and License Plate lights stopped working

With light switch on, test the wires leading up to the mentioned lights with a test light(cost about 5 or 6 bucks at wal-mart) that way u can eliminate any corrosion questions and get to the source quicker, if test light indicates that the wire is hot, than check connection areas for any wear and tear and possible carbon corrosion. Check lightbulbs, my license plate light stopped working and wire was hot, but wouldnt turn on due to the housing base, got too dryrotted and wouldnt function propery, had to rig it up, but works now.
