I purchased one for my T31 from Amaya Trading in Japan (Genuine Japanese Car Part Imports - Amayama) it was a genuine Nissan part at almost half the price of a UK sourced part at £17, 3 years ago incl shipping costs . Took just over 2 weeks to come. Go to Partsouq (https://partsouq.com/en) enter your VIN number or search model, takes you to exploded parts diagrams and, from there, part number and suppliers. Put the part number into Google etc.
The fault on my car exhibited as difficulty starting when it had been parked on a slope overnight. The bulb was found to have a hairline crack in the neck where it fitted into the clip.
Non original Priming bulbs on ebay ,can you install one of those or look for someone dismantling an Xtrail .
