This may sound obvious but if it saves someone else hassle it'll be worth
it.

I bought some rather cheap bulbs from ebay for the 156.
One failed within two hours of installation and the other emits so little
light I had to drive home on the fogs.

I have now purchased a set of Halfords Xenon which although expensive ( they
had an offer, £24.90 each, buy one get one free. ) seem to be just the job.

I know I can get quality bulbs on ebay but I needed them instantly or I
won't get home from work tomorrow!
