Flasher relay alternative part?

Hi There,
this is my first post so apologies if it's in the wrong place. I need to replace the flasher relay (turn light comes on but doesn't flash) the part number i have for it is D3AB/1335AA but cant seem to track one down and was wondering if there was an off brand version or something from another manufacturer that could be used? I live in the UK so I just get blank looks when I talk to the parts suppliers here.

Many Thanks!!

Not really a relay, it's a turn signal flasher. Rockauto has them and they ship to the UK
In the link they're priced in British pounds.

BTW, welcome to FTE, lots of good people here.

Just so you know, up under the dash there are two flashers. One is for the turn signals, the other for the emergency four way flashers.
Try swapping them and see if it cures your problem.

Also if one of your turn signal bulbs is burnt out it wont flash the dash indicater or the other bulb.

I believe it can be called a relay as well. After all, "flasher" is not really the technical term for the device I don't think. Of course, just like a Ford starter relay being called a "solenoid" (mostly) incorrectly, I'm not sure what the original term for the flasher unit is. But it was called a relay, a flasher relay, and sometimes even a "winker relay" (sounds British?) in the forties and fifties. I saw it called that last one in writing up into the late sixties. Or maybe they weren't even a thing in the forties yet? The winker terminology never really seemed to catch on though since I've been around. Mostly I heard them called "flasher units" too, before I heard them called just plain "flashers".
But because it opens and closes a set of contact points to make and break the circuit, it is in fact one form of a relay. But instead of manually switching by the user, it's automatically opening and closing the contact points through it's own mechanism. Whether that happens to be thermal, or electronic, or whatever.

Anyway, just by way of starting a discussion. Not saying anyone is wrong, just wondering if anyone knows the old-time history of what they were called, or even if they were never officially called what they really were?

Make sure to follow Mikes advise, swap the two flashers to see if your blinkers start working. I just went through this on my truck. I replaced one and it didn't fix the problem. being the smart guy I am I decided it was the turn signal switch and replaced it and found they still didn't work. I then did what I should have done in the first place and traced the wiring, which led me to the OTHER flasher. At least I found a $60 switch at Roc Auto instead of the $350 switch at Autozone. The flasher is only about $10.
