Retro Fitting Front Fogs

Post by **Tim Leech** » Sun Mar 22, 2009 11:09 pm

I have a pair of OE front fogs from a broken BX Gti which I want to fit to my TRS, they come attached to the black plastic panels, is it a case of cut out a couple of slats and clip them on?

Many Thanks in advance.

Yes, but you will need to add the wiring to make them shine.

Thanks mike, just want to get them on for now as I dont have the switch etc, I had considered wiring them in to main beam. So I just lop off a couple of slats and they clip on? is it that easy

I think it is. IIRC the black plasic mouldings fit into the bumper when it has been trimmed to shape. May need 2 screws per mounting.

Look at a GTI bumper and you will see where to cut.

I have a fog switch and mounting if you need one here.

Easiest to put them in parallel with main beam, but a switch is nice so you can control them independantly.

Great stuff many thanks, will get the house moves done and have a look.

Cheers!

I would be wary of just wiring them up with main beam without a relay - as the current will all be passing through the stalk switch. It would probably cause a fair old voltage drop and may cause the switch to heat up/melt.

Good point, im not that good with electrics (i can change a bulb) so will get them fitted in and let someone in the know do the wiring, thanks for the advise.

Kinda makes them redundant as FOG lamps though....

I thought it was illegal to use foglamps if it wasn"t foggy! If this is the

case you might find yourself the recipient of unwanted attention from

Old Bill if you wire them together with the headlights!!

i thought that was the case too although it does not seem to register with most people these days ,you even get the chavs riding around with juat side lights and fogs

my original understanding was that driving lights which were linked to your main beam had to be above the bumper and fog lights had too sit below .you would be far better to fit the proper switch but also link it via a relay so that they wont work on full beam as it is recommended that you do not use full beam in foggy conditions.
There bet that stirrs up a nice bit of debate

Actually, if they're wired into the main beam, you can have anything you like on. The issue comes with leaving fog lamps on all the time when it's not foggy. My point was that having fog lamps wired in with main beam makes them completely redundant, as if you've got you main beam on, the pattern of light from a fog lamp will be completely useless.

Conversley, if it's foggy and you want them on, you have to turn on your main beam, which again completely destroys what you were trying to achieve.

Driving lamps with main beam is another matter entirely... That actually works.

Technically, you can actually use fog lamps as an alternative to dipped beam, even when it's not foggy, as fog lamps use lamp shields and hence have indirect light, but in order to be classified as a "dipped beam" they have to be a minimum of 500mm from the road surface, which almost no foglamps are.

Matt's quite right about the relay, BX wiring is so thin & flakey that just adding bulbs in parallel will probably result in zero increase in light power.

Cheers guys, I will wire them in to the main beam circuit but need to sort some relays out first.

And you really believe that will improve your ability to see in the fog?

The 'fog' lights on a BX do very little to help see better in fog IME. Actually, given they get used about twice a year anyway, their primary function seems to be making the car look higher spec'd.
