Direction indicator fault

Hi there, re. Daimler V8 250 - my front nearside (left) direction indicator stopped working mid-drive. There’s no “tick tock” nor green flashing “arrow” light on the steering column when the lever is pushed to signal left, but the rear left indicator flashes very quickly. Right signals work fine. Bulb seems ok. Has anyone got any ideas?! Thank you!

Chang the bulb over with the one that works , and put the one you think don’t work into the fitting of the one that is good , your know if its the bulb 100% then
If bulb is good , look under wing and follow the wire from the indicator , to first joint , see if that’s live !

Thank you. I’ll give it a go…!
