So -- If the Alternator is charging, the (D+) terminal has 12 volts on it; the blue wire from (D+) carries 14 volts to the "Alt" light in the instrument cluster. When the engine is running, there is 12 volts on the *other* side of the lamp from ignition terminal #15, so potential difference is only 2 volts and the bulb doesn't light. But, if the alternator dies or the drive belt breaks, there is no voltage on (D+) (looks like ground) and current flows from #15 thru the lamp to (D+), and the "Alt" lamp comes on to warn the driver of a problem.

Why Eartheasy no longer sells CFL bulbs:
We have discontinued sales of CFL bulbs because we are concerned about the inconsistent quality standards among overseas manufacturers of CFL bulbs, and the use of mercury in these bulbs.

The rapid development of LED bulb technology is bringing newer LED bulbs to the marketplace which are safer, longer lasting and more energy efficient than today's CFL bulbs. The price of LED bulbs has recently gone down to a more affordable level, and now delivers the best cost-savings over the life of the bulb when compared to CFLs or any other light bulb available today.

If you can't see spending what it costs for an LED replacement now, at least switch to a CFL to reduce your costs for one bulb life of about 5 years and then re-evaluate the situation then. It will reduce the amount of mercury that is released into the environment and reduce power demands.

When to turn off your lights - The operating life of a bulb is affected by how many times the light is switched on and off. Here are some guidelines to help you get the peak benefit from your light bulbs.
