I have a MK7. It's a motorcaravan with physically high level front and rear marker lights in addition to the standard sides and rears.
I always drive on dipped as 5w sidies are as much use as candles. "See and be seen" from both front and rear is my motto.
However I seem to be forever changing headlamp bulbs and they are also discolouring the headlight plastic lenses.
I bought a L&R pair of foglight brackets from Ebay. The bumper already has the mountings for them.
I bought a pair of OEM Ford foglights that came with both H4 lamps and LED lamps. Also from Ebay.
All I need to do now is cut out the pre-marked round holes in the bumper and mount them.
I intend to use the LED lamps which take very little current as DLRs, wired into the side lights.
If you fit those light bars mentioned in the reply post - I hope you use them only off-road as they would surely dazzle oncoming traffic!
