I can assure you the MC28 will never have left Honda with substandard lighting.
As Leigh says, your battery is probably shot, or the regulator/rectifier is dying, or the output from the stator is starting to fail. Other than that, it could be a short somewhere in the wiring harness that's slowly draining your battery.
Non-OEM batteries, or poor quality aftermarket items will often fail within 6 months in hot and humid climates. Until I fitted race fairings and removed the lights on my MC21, I rode tens of thousands of kms, and ALWAYS rode with the lights on. I've only ever needed to buy 2 (high quality) batteries in 18 years, and replaced the reg/rec once. (It's a known weak point on NSRs.) I am sure a myriad of MC28 owners here (and MC16/MC18 owners) can tell you similar stories.
The long and the short of it is the NSR250, ALL models, in ALL conditions, needs a strong battery in tip-top condition. This goes for road bikes and race bikes. The exception to this rule is the F-III setup, that uses "low draw" electronics, but still needs a well maintained and charged NiCad pack, or it will rapidly drop a cylinder and the RC Valves will fail.
