Modern Car Headlight Bulbs; Short Lived?

[Ed_Dinning]

Hi Gents, I guess there are a lot of bulb failures judging by the great number of vehicles on the road with lights out (how can you not notice that as a driver?) and with mis-aimed headlights.
This latter due to DIY'ers not certain of how to fit the bulb and happy that it is alight, even if not pointing in the correct direction.
