a bit of help if you can.

just got a mint cond siggy cdti 1.9 120 elegance. 56 plate, 38k.. well chuffed!

I have been living in canada for the past 3 yrs were headlights are on all the time while driving..i think this is safe as you can be seen more clearly. . if i buy an auto light switch will it keep the lights on all the time and bypass the window sensor?

If not, can i set up a relay with a switch to disable it (when needed) so the lights will work with an ignition live. or will this throw up faults on the dash?

many thanks.
