Pontiac: Headlight Malfunction

In article <google.com>,
com says... 

Have you tried spinning the dail? Sometimes the contacts go bad. Also
there is a sensor for day and night on the dash.

Relay going bad maybe?

is there a photo cell or electric eye on the bumber or probably on the
dash board of the car? maybee there is a blockage of light to it from
dirt grease or a piece of paper, stupid

It is possible that the ambient light sensor (located on dashboard) for the
twilight sentinel is faulted. I believe the body control module controls
these functions (security feedback & twilight sentinel)

Why would the ambient sensor cause the abnormal light flash problem when using
the remote entry fob?

Well, it doesn't. That light flash isn't really a prob. The light flash is
a function (result) of security feedback & the fob.

I interpreted part of what "Bon·ne·ville" wrote in his/her post as meaning that
the tail lights no longer light up when using the remote fob either...so I
assumed they used too at one time. Bon·ne·ville's comment:

" When using my remote entry, I noticed a flicker in the headlights
(during the unlock/lock report) and the tail lights no longer
turn-on at all."

I _think_ "Bon·ne·ville" is trying to say that the light feedback report
function (from activating the controls on the remote fob) are not working as
they used to work...that the tail lights used to light up (flash also) when
using the fob and now no longer are. Perhaps he/she could clarify?

If my interpretation is correct (and it may not be) then I don't think the
problem is from the ambient light sensor.

Whoa wait what? Those arent my quotes. I was addressed the twilight
sentinel problem only. Not sure why the taillights no longer report
other than burnt out bulbes. Havent looked into the wiring diagram on
any of that yet because I've never seen or had that problem.
