Think its time to consider buying a new lighting board ... the 7 core cable has once again gone as curly as a telephone handset cord.
Raises a couple of Questions...
I notice that you can now buy LED lighting boards .......
Be interested in views of any that own these, and do you think they warrant the extra cost ?
Secondly boards are available with Reversing lights ... these worth having, or not worth it.
I am not sure if you can get LED and Reversing together (obviously no technical reason why not)
