Geoff,
The ones described on your link look to be identical to mine. However, mine were eBay Item number
191435078217. If you Google this number you should get the relative link to, probably, ebay.com
and not ...co.uk, which may not share the same numbers for the same items.
Just ordered these ones and they seem to be a direct replacement for the original lights.http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=251742082764
