Hi all, I have posted a question about this before, but actually have to do the job tomorrow in readiness for the MOT - I have front driving light on my XR, but have yet to wire them in - I understand that its a fail point to have them on the car, but not working. Anyway, I was advised that I needed to wire them in using a relay and a feed from the mainbeam headlights. Can anyone provide more detailed information about relays? (ie - I dont really know what this does / how to wire it in?? - something I've never had to do before....) Bit of a novice in this area!! Thanks in advance, Ed.
