I have changed the red MFU module in the rear of the interior fuse box for another. Neither make any difference. Yes, they work well, but should only be used for their intended purpose - to help increase your visibility in poor climatic conditions. 3. Do all cars have fog lights? Just in case you’re struggling to find the rear fog light switch or the rear fog lights themselves, I thought I’d go through some common installation options for both. Fog lights are also not to be used when it is wet, as the extra brightness of fog lights can result in their reflection off a wet road surface, and can cause unnecessary dazzling reflections, which is not good. I have isolated the OEM wiring circuit diagrammes for the rear fog, including the position of the relay.
Take a minute to see if your car has rear fog lights. Put the car in Park, turn on the engine and then turn on the headlights. Walk around to see how your car looks with just the headlights switched on from the rear. See the pattern of the taillights? If you have someone who can help you, have them press the brake pedal so you can see what your brake lights look like. Now push the fog light button and return to the rear of the car. Notice any brighter lights that are similar in brightness to your brake lights? Then you’ve got rear fog lights as well. Now that you’re aware of this, using them should be restricted to poor visibility conditions — and not to annoy the poor guy behind you. Feel free to illuminate your headlights, driving lights and even front fog lamps (if they can be turned on independently from the rear fog lamps), but save your rear fog lamps for foggy weather. The switched circuit of the relay gets 12v live feed from a splice into the n/s rear side-light wire, the switch "on" terminal connects to a splice into the n/s fog-light wire. In the UK, street lights on 30mph roads are placed no more than 200 yards (183 metres) apart. So a good rule of thumb for using your fog lights is whether you can see the next street light up the road from the one you're passing. Use this rule, and it's clear that it's only going to be in the foggiest or snowiest conditions that fog lights should be used. Full compliance with this guide doesn’t guarantee a pass. You’ll need to view the IVA Inspection manual for the full requirements and testing procedures needed to get your vehicle passed. its all so painful - the official toyota rear fog fits into the small 'quarter' panel that clips to the bumper and sits under the rear lights, I suppose I could buy that panel from amayama, but it looks a little naf, unless I buy one for each side.It is small and square in shape and sits on the right hand side of the engine, to the right of the battery, forward of and slightly lower than what looks like the ECU. Although immaculate looking and low mileage the car has had a hard life. It had a new offside quarter panel fitted around 3 years ago. If it's not a common fault i'm wondering if the two things are related. Hi, this is a very sensitive topic, with boths sides, ( single of dual), making their cases for why. I have seen your reasoning given over and over again, and the other school of thought has something they beleive justifies two lights. I have some links for you to read, I left them at work, and rather than google all these things over again, I'll post the links from work tomorrow. Basically, the argument FOR dual rear fogs is centered strictly around using them ONLY in cases of severe fog. The dual set up improves visability for the following driver, (he will see you sooner), and two lights set far apart gives depth perception to the following driver which a single light can not give. Using them at the proper time ought to aid safe driving, however, their usage when unwarranted can mean that you are breaking the law and endangering other drivers.
If you choose only one rear Fog for your reasons, thats fine. If you choose no rear fogs at all, again thats fine. The fuse box under the bonnet seems to be different to how you describe...wish I could share a photo. TOP TIP: If you don’t have a helper, park next to something reflective. A wall or garage door will do. Drive extremely carefully when the roads are icy. Avoid sudden actions as these could cause loss of control. You shouldwatch out for snowploughs which may throw out snow on either side. Do not overtake them unless the lane you intend to use has been cleared The important point here is about obscuring brake lights. Rear fog lights are brighter than standard tail lights, so when you brake, other motorists may not be able to see your brake lights illuminate. I'm concerned by activating the airbag by mistake when connecting the wires to the new unit (I don't really understand how the airbag is activated / what safety precautions I need to take) Anyway here are a few links, but just don't let others lead you down the path, get on google and do some homework yourself. when i took out the 3 rd diode,furthest to the right,my head lights work,but the alarm to tell me ive left my lights on,no longer worked
Great Deal
