Nissan Altima engineering gripe

I don't understand why a fully loaded 2008 Altima 2.5SL would have cut
outs for fog lights and no option to purchase them (it seems that this isn't
a new problem as ng discussions point to this being the case in former
models also).  Does anyone know why this happened?  When you ask dealers
about it, they almost all say that it's impossible to upgrade when the
reality is that many of these cars (mine included) have the harness/column
wiring for the fogs and simply need the lights, brackets and a new light
stalk.  If anyone here works anywhere near Nissan R&D - How does this
happen?  On the plus side, it's a great vehicle and this is likely my only
gripe.

Thanks for listening to my rant.
Andrew.

Usually there's more to it than that. For example, Nissan's with
foglights also have beefier alternators. Foglights by themselves add
an additional load of 10 amps.

Only when they are on - which should be almost never when used
properly.

Exaclty . . . . "used properly" which is almost never.
Also, it doesn't matter if the fogs are off most of the time. The
alternator must be chosen with a amperage capacity such  that it can
handle a full load even if it is ever so brief. If the AC, rear
defogger, headlights and fog are on at the same time, the ALT has to
handle the full load.

I would think the amp on the Bose system would create a similar excess load
so it would be reasonable to upgrade the alt on the Bose system optioned
Altimas.  Now, what's reasonable and what's acceptable to the OEM are
sometimes two different entities.  Either way, even if the alt did need more
windings or better built rectifiers, the option should be available.  You
would think that the OEM would allow the purchaser to make the decision.

Thanks for all your comments.  I am going to go with parts from a 3.5SE and
I will let you all know how it works out.  I can put a DSO on the alt and or
fog circuit also if you want.

Thanks,
Andrew.

Bose systems in the car use high frequency (>100 Khz) switching amp
technology. Basically, it's an AC power amp, and it's extremely
efficient. If it was a DC based amp of most car audio, its power needs
would be tremendous.

As for the options game with Nissan, I feel your pain. Try adding just
a sunroof and Nissan say you have to get the comfort and convenice
package which includes leaterher seats, Bose stereo, carpeted floor
mats, yada yada.

Thanks for all the advice and guidance.  I have installed the light stalk
from a 3.5SL and I have the foglights in the mail.  I have confirmed that
both of the foglight harnesses are intact and tucked behind the bumper (one
is under the wiper reservoir and the other is taped to another harness
inside the front fender well.  If there's any interest, I will report back
in once I have installed and tested everything.  I will run a check on the
amp draw vs the output on the alt also.  I don't intend on driving around to
the mall fogs on - I commute along a shoreline for over an hour daily and
the fog can be relentless at times.

Thanks,
Andrew.

Thanks for all the help to those who responded.  I have now installed the
new light stalk and have the fog lights in my posession.  I will install
them over the weekend and let anyone who has a remote level of interest know
how it progressed and what the real word amp draw difference is.

Thanks,
Andrew.
