I had the ones with 3 modes but didn't like them, found them a bit small And had to cycle through modes, the twin switch was naff. I sourced a grey switch to match switch gear and wired fogs via relay/switch. Fitted an led 501 bulb to sidelight that was canbus ready, just chopped into side light wire for halos and the resistor in the bulb does the rest! no faults at all!
