I had a similar thing happen in my 182. I had a digital voltmeter that
was set to turn on the high voltage light at 15 volts. For the first
couple years I owned it the voltage was always at about 14.5-14.7 during
cruise. It started to inch up and occasionally touch 15 volts thus
tripping the light. replaced the voltage regulator and the problem was
solved.

It's a Cessna 172M, and the battery was just replaced in the last 6
months (not to imply that it's okay because it's new). It also just
came out of annual in February...

Other than make/model, was there any additional information you were
looking for that could be helpful?

Thanks!
