Thank you very much everybody for your help. I agree that sidelights should not be used for driving! But it is good to have them working anyway. As English is not my first language, I am unsure of the difference between parking lights and side-lights, but I think I am referring to the side-lights (i.e. not the orange flashing ones which indicating turning left or right, but the dim white front lights which are the first to switch on when you turn the left stalk).
I'm wondering whether it's possible to swap the blown out 510 W5W 5W bulbs with LED lights - and maybe do the same for the main beams too, in case the whiteness changes too much. I've done a bit more research but still have a couple of questions:
1) I am assuming LED lights can indeed be used, and I do not need to buy 'Canbus error free' LEDs?
2) Can I use a LED which only uses 1 or 2W? Is using a LED which uses 5W too powerful (i.e. is its light too strong?)? I have found the following 6 options on eBay (in increasing order of light output - sorry I cannot post URLs yet, so I have given the current ebay item number!):
eBay item number:301236451220:
(12V, 43 Lumens [LM])
eBay item number:140825715721:
(12V, 72 Lumens)
eBay item number:311059797702:
(strange socket, not sure if compatible, DC 12V, Lumen output: 100-150 Lumens)
eBay item number:301294897793:
(1.5W, 250-290LM)
eBay item number:331348796146:
(12V, Lumen output unknown)
eBay item number:131360258641
(DC 12V, 1W, Lumen output unknown)
Sorry for the many options! But in case you've taken the time to check them, my question is: are they all OK, and do you have any suggestion and to which one to buy?
3) Which bulbs should I buy for the main lights please (socket, voltage/wattage), in case I want to upgrade them as well (it's probably time to change them anyway)?
4) (edit) Also, I've noticed one of the two front fog lights of the Sporting has failed - again, does anybody know the specs for the bulb I need please?
Many thanks for your help!
