Re: [Amc-list] Headlight Malfunction / Question

[Wrambler242@xxxxxxxxxxx]

When one lamp on a circuit dies and is replaced the load on the circuit changes due to different flow on the new lamp. The other lamp or lamps will follow along and die if they are anyway near the end of their life.
  We had three clip lights plugged into an extension cord in a construction hall. I soon learned when one burned out replace them all. Then they would last a good while. If I only changed one it was never ending circuit of changing those three lamps one after another!
   Our Theatre lighting tech says the same with house lights. They all come on and go off at once, when the hall reaches about 20% failure many venues change them all at once to save setup and man hours.
   I have to replace the lamps in our 98 Altima, they are dimmer than trying to see out a tinted windshield on a rainy night! 10 years old and neither has burned out, but the light produced has sure decreased!
