Help me out please.
fitted two rear outline markers today, onto a chereau fridge trailer. fitted lovely and wired into existing blade receptors.(there were several of these but I connected to the ones that the existing marker came out of)
The problem is on the n/s marker, every time I brake or indicate the marker flashes. somebody got any ideas of what to do■■? 
thanks in advance
It’ll be earthing out fella much like on a car … recheck the wire old and new
nice one, i thought that it might be a grounding problem but i,ve only attached the wires where they originally came from so was unsure

just follow that one set back and you’ll find its prob got a split in the wire casing and shorting out . you could just go back to a join and cut off the old and splice a fresh set if wires in.
