A variety to be honest! Newer Ford Mustangs / Chevrolet Camaros are common
As a background we ship vehicles into the UK, mainly from the USA. The lights have to be converted to UK spec, mainly this involves separating the brake feed from indicators and then changing to amber flashing bulbs, either using LED to flash through red clusters or using the clear lens that usually hold reverse lights and then using dual colour LED to function as indicator and reverse
If we can get the car to stop performing the default action for brake / indicator using + spoofing CANBUS signals, perhaps we can do this easier and with less wiring than current method involving relays and feeds from brake switch etc
I hope it is possible!
