5. I cannot describe how much I hate permanent on lights. Considering that scooters have quite low capacity batteries, they could have installed also a circuit that delays turning on the lights AFTER the engine is running. This is coming from somebody who rides 365 days/year and starts scooter (I have no garage) that was maybe covered by snow during the night.
I think i saw somewhere you can buy this electric unit that delays lights coming on for the first 30sec, while the engine is warming up. It was a product for sym 400cc if I remember correctly. Maybe see auto electrician too.
