W5W the same as t10

[robmc]

Can anyone tell me if w5w globes are the same as the t10 parker globes in my vy ss?

Just picked up some new h4 philips x-tremeVisions and there is a pair of them in the packet.

I searched and found some info that w5w globes go in the projector headlights but nothing about standard ones.

Cheers
