So I’ve partially found out what this ‘hella transflash’ thing is for.. It connects INLINE with my existing flasher relay, between the relay and my trailer socket.. Idea is twofold – 1) IT drives the trailer/caravan indicators, so it doesn’t change flash rate, and a short doesn’t take out the main indicators on the ute.. 2) If a globe blows on the trailer/caravan (I haven’t confirmed this by testing yet mind you), that little red light is supposed to light up.. How that works, I dont’ know 🙂 When I test it and find out, I’ll post back!
