Problem with rear light bulb?

Hi there,

I have a Renault Clio (52) and replaced the rear brake light as it wasn't working. The new bulb isn't working, and now the reverse light isn't working either. I was told that I need a new circuit board. Does anyone know where I can buy one from, instead of going directly to Renault who may charge a fortune? I rang them today but they're not open during the weekends.

Any advice would be much appreciated!
Thanks.
