The first thing you should ck is your ignition. The vehicle may need to be re-keyed. The ignition switch could also be broken. This tends to occur especially by using generic copies of the key. Sometime they are not made to the precise specification.

The higher the rated wattage of the bulb, the greater the luminous efficacy, which means you get more lumens per watt using a 120-watt bulb than using two 60-watt bulbs. Check the lumen ratings for the two 60 watt bulbs, and compare it with the lumen rating for the 120 watt bulb. That should give y…

Dimmers can cause ceitain light bulbs to be noisy due to the way the triac based dimmer chops up the ac sine wave. Different bulbs use different filament structure. The chopped up sign wave can set up vibrations in the filament structure. Some filament structures vibrate more or less.

The wavelength of ultraviolet light is between 10 and 400 nanometers (nm).From the wavelength you can determine the frequency. If you divide the speed of light by the wavelength, you can calculate the frequency. The frequency range would be from 7.5 x 1014 Hz to 3 x 1016 Hz.

Of the colors in the visible spectrum, red has the lowest frequency and the longest wavelength. As you move on "up" the spectrum, wavelengths get shorter. Red has the longest spectrum of all visible light. But infrared is even longer and there are many more "colors" but you can't see them.
