Canbus and Relays

Afternoon.

I'd like to fit an auxiliary light system to my 2012 Fabia Elegance Estate. The car is used as a motor sport support vehicle at night and as most will know, the lights aren't brilliant.

What is the best way to wire a system in, please? I am mindful that any extra load will cause canbus issues and would like to avoid these, are there specific canbus relays etc?

Thanks in advance for any help.
