It seems a bulb has gone on the front of my Octy, How many bulbs are there in the front light assembly? The engine is hot so would rather not go poking around to find out. I am guessing the H4 is just main and dip? then there is a Fog light bulb as well? is there a third bulb to provide the sidelight? or is this part of the H4 bulb as well? as it is the sidelight that has failed what part should i be ordering? and is there any company that i should order from?

The sidelight is indeed a seperate bulb (std 501 capless bulb)

If you just want the sidelight back then any motorfactors will carry them.

If you want to 'upgrade' them to either blue, or LED's then they can be found on eBay

Also worth looking on powerbulbs.com Briskondians get 15% discount and get free Philips Bluevision sidelights with any order.

I'd agree with the Powerbulbs recommendation.

As earlier H4 head and 501 capless or wedge sidelight bulbs. 55W H1 front foglight if applicable, and 21W orange bulbs for the indicators.
