could be several things, I would start with the dimmer switch.
I have a 2000 olds alero and the signal light only work sometimes, What would cause that?
The Astro was discontinued in 2005, so I'm not sure what a 2009 Astro would be.
The security light on a 2001 Chevy Astro Van can be reset by disconnecting the battery for 30 seconds. This resets the system and turns out the light until another problem is detected.
The ray of light hitting a mirror is called an incident ray. It represents the path that light takes before it reflects off the mirror's surface.
Light sensors measure the number of photons or the energy of light hitting the sensor.
Yes, urinary tract infections can sometimes cause spotting, which is light bleeding between menstrual periods.
Yes
The cause of the tail light burning dim when the light switch is on could be a short in the wire or an exposed portion of wire. This can sometimes cause the bulb to lack power because the power is drawn to another area.
Light sensors measure the number of photons or the energy of light hitting the sensor.
5.5 light hours is about 40 astronomical units (AU)
The light reflects or refracts on hitting the medium.
The width of the light source is the main cause of the shadow edge becoming more blurred as the mask approaches the light source. But light refraction around the edge of the mask may also be a minor component.
