Just a few things I've noticed recently whilst driving and just wondered about different scenarios. Running lights you know those LEDs that come on when you put your ignition on??? What purpose do they serve? It seems to me like people think they are ok to drive on in all weather conditions. I've seen them being the only lights on on cars in Fog,rain, darkness inclement weather so my questions are this. What is the legality of driving on these lights, my personal take on things are that there is no change to the use of lights as stated in the Highway Code and that in inclement weather the legal requirement would be dipped headlights as for night driving. I've seen people driving in thick fog on running lights and Fog lights again the legal requirement is dipped headlights and fog lights. And just two nights ago I was passed on the M1 by a car running on these lights and after he had passed me I realised that he had NO rear lights on at all! So do they only light up at the front or what. My very personal opinion is that they are an extra that manufacturers have put on their cars for the look factor ie look at my new Audi that daddy bought me it's got lovely bling lights on the front but I don't know how to use them. So has anybody got any thoughts on these things be it the legal side of their use or anything else.
