Are HID headlight bulb systems legal in Spain?

Headlights are not on whenever the ignition is on. It is the daylight running lights which are on and these are LEDS.

Speak for yourself. My car does not have LEDs but does have daytime runners. (VW Polo). If the ignition is on, the headlights are on - on low beam. Like the old Volvos. They can be deactivated but I think they're useful; though heavier on bulbs. But thanks for the advice.

@Guy i live in Madrid, unfortunately no Halfords here.

Also my corsa isn't LED just the normal style bulbs 

I changed the passenger side main beam bulb with a standard bulb for now as i had a spare.

On the 2006 opel corsa C the battery is located at the back of the engine bay (upper left.)

Behind the drivers side headlamp is the fuse box and on the passenger's side is the air filter. The passenger side was very easy to change but driver's side is a bit more difficult to get to as the fuse box is in the way. When i change both later this month i will inform you all how it went. How many new Spanish swear words i will have learned too!
