Wiring my vw scirroco headlights direct to the battery in near white out conditions along the Trans Canada in Saskachewan in February (-30 celcius). Its nice when your lights suddenly fail at 100km/h in a snow storm (relay blew chunks).
I scavenged enough wire from interior components that no longer worked, spliced it together and prayed for no fires. I had loads of snow to roll in if things didn't work out
I might thnk of something else later. I'm sure Winfred willhave a gooder.
