Hi guys,
Sorry, I know I've been asking a lot of silly questions of late

Just getting close to finishing the resto now so just ironing out all the silly kinks!
When breaking and indicating my rear light cluster flicker. The brake lights don't stay on solidly, they flicker and the indicators flicker on and off as well! The front seem to play up and do a similar thing too. Noticed this when having my MOT done (helpful!), but lucky my MOT tester is my brother in law, lol.
Any ideas on a fix guys? Grounding the lights, cleaning connectors maybe??
Cheers chaps
