Towbar wiring query

Morning

I have an issue with the indicator on a trailer I have just bought and I think I have traced the fault to the relay that is already fitted.

I have tried to find a direct replacement for what is fitted but it looks like the company does not exist any more, so I have found a relay on Amazon ( Replacement Relay) and was wondering if I can use this as a replacement and will this work alongside TEC3M relay.

Any help onthis would be greatly appreciated

Have you checked the earth to that particular indicator bulb?

I have checked the trailer and it is fine; I have tried my car with a couple of other trailers at work and it has the same problem with the indicator not working.

I think this explains the buzzing at the back of the car that I hear every now and again but I could never trace where it was coming from and apparently these relays give off a buzzing noise
