All ignition lights occasionally flash on whilst driving, does anybody have any idea on what could cause this, maybe a possible relay?

Thanks

What year is it?

Actually, I doubt it matters - typically if you have all the dash lights flickering, particularly in time to wipers being on, indicating, using hight beam, etc. basically anything drawing a large current, it is down to either the alternator or the batteries.

You first stop should be to double check all the wires to the batteries - check the connections on the batteries and then chase the wires from the batteries and check the connections on the other end.

With the negative wires from the batteries that bolt to the engine or body it is worth undoing them and then applying coppereaze to the bolts and then do them up again.

If that doesn't fix the problem, check that the alternator is working properly - the chances are the brushes are worn out - if the alternator isn't producing enough charge, take it down to a local auto electrician and get them to check and swap the brushes on it.

The above should sort the problem - if it doesn't get the batteries checked as well.
