I have a @09 TERIOS(love it) and had tow hitch/single electrics fitted by a locally very well known agent.
It get's interesting though!!!-- WHY IS IT ALWAYS THE RIGHT SIDE????
My trailer which is fairly new has TWO sets of lights - lower & upper:
INDICATORS work fine: SIDELIGHTS work fine: BRAKE lights work fine:
FOG light is fine: BUT when I switch on HAZARDS - whoops!!
I get one very fast flash, then nothing. I UNPLUG the trailer and the car
hazards work again. NOW I have to replace offside indicator bulbs EVERY time this happens.
( I had similar with a vauxhall before,but was just constant replacement of offside indicator bulbs).
I there a relay which is being overloaded/tripped??? - handbook is not much use!! HEEEEELLP


It turned out the problem was simply that the flasher unit was overloaded. BUT you try finding a heavy duty 8 pin flasher unit!!!
I overcame the problem eventually by fitting LED lights to the trailer so now the flasher doesn't think it has any extra load---- problem solved - now ALL my trailer lights work.

Do you get a response from the dash trailer warning light, a legal requirement, when a trailer is towed. ( flash once when trailer not connected, then in time when trailer connected)
