Now I've found out the range rover sport doesn't like caravans/trailers with led taillights!!

Got the new tin tent and wifey says why are the hazards flashing, I'd noticed the reversing aid hadn't tuned off.

So the solution is a 7 way bypass relay or fitting a normal bulb somewhere on the caravan/trailer.

Has anyone done either?

Does the 7 way bypass get wired into the carvan or the sport?

Is fitting a blue inline with an indicator going to work?

Thanks in advance
