I am a new S80 owner and I have a question about the rear fog light. Is there only supposed to be 1 bulb on the driver's side? It looks like there is a bulb holder on the passenger side, but the bulb won't go in.

I'm just wondering if something is missing or if it is just a one sided thing....first car for me that has a rear fog light.

Thanks.

 

It only works on one side that is the way it is designed.

 

hey tech, why did they do that? what could be the reasoning for only having one bulb light up?

 

Most autos built in Europe have one rear fog lamp. It is always located on the left (drivers) side of the auto. There is NEVER two bulbs showing to the rear............only one. Audi, BMW, Mercedes, Volvo, Saab, and the list goes on use this system. If two bulbs are lit, it would appear as brake lamps, hence, only the left rear as the vehicle is being operated.

For exactly that raeson.

 

When you have two, you have the light from the one on the right side reflecting into the drivers view. If you have one on the left, pointing to the right, it will hit the fog at an angle creating no reflection towards the rear view mirror. It is also very bright, so keeping it on when people are behind you would be quite rude.

 

You can easily add another bulb to the other side - the wiring is already there. All you have to do is cut out the plastic with an e-xacto knife so that the bulb fits in. You will see an outline of where to cut if you look carefully. I did this on my S80.

 

You might want to check if it is legal to have two of these lights.

In Canada you are not allowed to have two of them. There is a reason there is only one and it is so people dont get them confused with your brake lights.

 

Yes, this is probably correct. I rarely use my rear fog lights. I just wanted to see how easy it was to accomplish this.
It aids in visibility when backing up in dark places when leaving a parking area.

 

I have heard from people getting pulled over here in FLA. and getting a ticket from driving with it on on a clear night.

 

Getting pulled over for fog lights??? Hum, seems that those stupid High Intensity lights in the front of the car would be more of a reason. Especially people that simply just change the bulb and not the entire head set.

It does seem to possibly be a law in certain jurisdictions of the USA (but it seems to be near impossible to get a reading on this one) that people are not allowed to use two rear fog lamps. Each state seems to have their own traffic laws and there are some strange laws out there - like the ability to make a left on red in certain states, although both streets must be one ways in most cases.

The rear fog lamp issue is a strange one, the police themselves probably can't give you an answer let alone the morons at the Department of Motor Vehicles. This to me is one of those stupid bureaucratic laws that makes no sense. In the European Community the law is the complete opposite. Every single car MUST have rear fog lamps. I tend to go with the Europeans on this one, preferring viability in hazardous situations over a crash...but just my 2 cents.

 

I live in the mountains near a casino and there a lot of rich ****** going threw winding hills riding your a$$ allthe way up so i cut out the right side put some super bright led bulbs in both spots and that took care of the ****** now when someone gets on my A$$ i get on the lights and they usually back off about 6-12 car lengths is atually very ver bright about 3 times as bright as brake lights only use them for those ****** though
