René if your problem is within the headlamp it's connector is the one below the new three pin connector I installed for switchback LED's in indicator position. Its a similar Econoseal 4 pin connector.

With wheel off it can easily be seen. Remove cable ties then press in plastic release to allow the connector to be parted. Clean and re-make.

Check also that tyre on full lock has not chaffed the wires. You can see some sign of the chaffing on mine. I recall adding some extra cable ties after the photo was taken. Note my new wires for switchbacks are protected by plastic spiral.

If your issue is with both dipped beam headlamps then it's probably the light switch stalk on the main/dip toggle that's become intermittent. Note unlikely to be a fuse issue since each headlamp filament is fused individually left and right. If this is your issue then check out this thread on replacing stalk.
