I fully support the views put forward by K K Fong (Sunday Morning Post, November 3) who drew attention to the selfish use of vehicle fog lights, causing the temporary blinding of oncoming drivers.
The use of fog lights is illegal in some countries, other than in conditions of fog or heavy rain. The reason being that, unlike standard headlights which are designed not to dazzle when dipped, fog lights in clear weather cause confusion to oncoming drivers as they cannot be dipped.
The density of the fog or rain lessens the discomfort when used correctly. But how many foggy days do we have in Hong Kong?
Observations show that around 20 per cent of cars in Hong Kong run with fog lights turned on, including taxis. This latter group, almost without exception, uses fog lights in addition to its regular driving lights at all times and for some strange reason, these lights are mostly orange in colour.
I have seen other drivers using fog lights only, which is not only dangerous, but probably against the law.
Similarly, rear fog lights are awful to follow behind.
