Thread: D2 trailer light flashes- no trailer connected

Hi guys,
wired up an LED light bar yesterday on its own provided harness
(so power and an earth)

however since doing so- perhaps I haven't noticed before then-
the green trailer light on the dash flashes with the indicators, despite there being no trailer attached.

I did change the trailer plug to a 7pin flat from the 7 pin round a week ago but haven't noticed the light before then- I left the 7 pin round connected as it had 3 other larger gauge wires running into it(didnt want to terminate them and will eventually run both styles of plug), which look to have been for a camper trailer or the like(perhaps a brake controller) but as i said, hadn't noticed the dash light until this morning.
(drove it last night after install and didn't notice the light)
The only other thing ill mention is that i accidentally shorted the system while trying to remove the fusebox- but ive driven since then and all systems are still OK.

Ive checked all the on vehicle indicator lights- all good, and the under bonnet trailer fuse is intact.

Any other solutions?

Cheers guys
I knew a bulb replacement was the way option but I was gonna try find a replacement unit first
