Flickering Instrument Cluster

[SpraygunJas]

Hi all, I've recently purchased a 2012 Delta 1.6 SR, Pleasantly surprised with it especially the interior dynamics however it's got a few niggles... The most troubling being the centre display in the instrument cluster flickering, checked the battery and alternator they're fine, yesterday the illumination at the top of the speedo started flickering aswell. I've noticed the n/s rear light has has the lense drilled and glued in the past, all appears to work now though. Has anyone else had the dash issues? I'm putting 2 on 2 together and presuming it's probably related to the rear light. Thanks in advance for any info.
