Perhaps your voltage regulator is broken. Elevated operating voltages
dramatically decrease bulb life. With the engine running and the brake
pedal pressed you should have 14.5 V +/- 0.6 V measured at the battery,
regardless of RPM. If the voltage rises above 15.1 V as you increase the
RPM, the voltage regulator is broken. (Voltage numbers from '94 Civic
service manual, doubt your Accord would be different)
