I thought I was being courteous by switching the headlights off and going sidelights only once I get into the sidestreets.
No, you’re being unhelpful. Sidelights are for parking and are a pointless invention.
– You run the risk of forgetting to switch the lights back on if you drive into a darker area.
– What if the street lights go off?
– You also look muich dimmer than other cars at the same distance (in every sense of the word).
– Nearly all running and cycling gear has reflective strips on it which only works if a driver has their headlights on.
– If one lamp goes the only thing to make your car visible (and I bet it’s grey or black) is a single 5W bulb.
– Cats eyes won’t reflect.
– The police may think you’ve been drinking.
– People will pull out in front of you.
– In conditions will multiple light sources you’ll actually blend in.
Provided your headlights are properly adjusted there is absolutely no benefit to driving on sidelights only. If you’re being dazzled by other lights in a brightly lit area, you may want to consider an eye checkup as it can be a sign of developing cataracts.
