Thanks
@Andy J and
@wireman , I asked as earlier this week installed new and re-wired the front side and indicator lights + have had new super-duper LED bulbs arrive from Better Car Lighting [very high quality British designed long life jobbies
https://www.bettercarlighting.co.uk/index.php]. Yesterday thought best to inspect rear lighting and wiring...it's all tired and needs refurbishing...that's this week's evening tasks and to make up new rear loom before fitting the bulbs.
I'm thinking I might add a reversing light that could double up as a rear spot light...engaged with reverse gear and parallel wired on/off rear spot switch
