A quick thanks to those who posted on this thread. I had the same issue with my front nearside indicator this morning whilst driving in the Purbecks. Found out the cause was the washer failing as when I pushed the bulb back a bit further by hand it worked. I disconnected the male connector under the wing and was on the verge of buying a replacement unit with the help of this thread when I took a more careful look at Gordon's fix and though why not have a go 🤞, I managed to make up a replacement washer from odd and ends I always tell myself will come in useful ... put it back together and so far so good 👍.
