Trailer Parts - Lights

[stevos]

I need to replace one of the bell-submersable (airlock) type lights on my trailer and am wondering if anyone knows if you can buy just the side you need or even better just a single housing?

Whitworths and BIAS only stock them in pairs with the buld inserts already in place. Considering I only need the housing it seems a waste to have one lying round the house as a 'spare'.

Alternatively anyone need a port side light and want to split it?

Cheers,

Steve
