Hi folks,   I'm new to the forum as I'm looking for some help.  I have a '04 plate C8 2.0 HDI (yes, the cam belt went last year and cost me a fortune..) but have bought a bike rack which obscures the rear lights. (I used to just bung the whole families bikes in the back but now the kids are getting bigger, so are their bikes!)  I therefore need to add a light bar and was wondering if anyone has experience of wiring in the electrics.   Would a universal type wiring kit be OK to use and is it a relatively simple job or one for an expert auto-electrician?  I am comfortable with basic car servicing but definitely not an expert!   Your advice and ideas most gratefully received.   Ed
