Got the tail light warning tonight and i know at some time i had bought a spare.When i replaced the taillights last time i did the pair.When i got home i renmoved the old bulb and cleaned/polished all the connections before replacing the bulb I jumped in and turned on all the way to check that all was well,no warning and voila taillight.As i walked back to turn off i heard ding.....and <tail light> was displayed.....wtf...went back round the back,and the OTHER side had gone!!!!!I had noticed the OLD bulb was much dimmer than the new one....so another pair of bulbs to moorrow one for a spare.I have a spare tail,brake and H1 for a head or foglight..
