i'll pop into Halfords tomorrow, they must have it! crazy price though 
I'm sure you will be able to get them, if not from halfords try a motor factor, they should be around a fiver each,
Markie, last year i bought 2 LED sidelight bulbs, 4 LED Indicator bulbs and 2 led stop and tails + the loading resistors, installed them and when i tried them they were crap! you could hardly tell in daylight that they were on (dangerous) and these were supposed to be direct replacements with 36 LED's around the side and tops, in my mind a complete waste of 60 quid, so I ended up putting all the original bulbs back in.
There's nothing wrong with LED tail lights BMW, MERCS, RANGE ROVER, and others use them, but these are designed on printed circuit boards and are very efficient, not like the bulb replacements.
If you want to go down that road, Make sure you see them working before you buy them, then you can make your own mind up
