At last I have managed to get hold of two replacement headlights for my wrecked 172 headlights. I managed to get the drivers side headlight ages ago which had black casing and I managed to get the passenger side headlight only a few days ago but I come to open up the box and get the light out I notice that the headlight has a grey casing. Would you put these two new headlights on your car or leave them and sell them until i find a new pair of matching headlights. The headlights that I have on the car now are in really bad nick and want them off the car as soon as possible as there is moisture within the light.
