I have installed the components in my old Golf IV 1.4. In the lower outer ventilation grille. Fog lamps are not built there.
The plastic had not sawed. The mount fits in exactly. The bulbs are out about 2mm.
But is not a problem. It thus remains hanging anywhere and the bumper is more about.
The light is very bright and turning off at "light on" works great.
Initially had concerns that the lights do not mix well with my gas system, since here too someday current is drawn from the battery.
.... but no problem.
Even the LEDs (described in some forums), if you turn off the engine still puts eg a Navi in the cigarette lighter, does not occur to me on !!!
Perhaps this is to a newer version of the controller.
Absolute buy recommendation!
Rather spend a few euros more, save money and have a lot of trouble!
