Went on Amazon and bought an endoscope that connects into my Samsung or any android phone. It was only £10.99 and has 6 led lights. Anyway I wasn't expecting much but it's come today and I must say its a really good colour picture and waterproof, it's also 1m long so can reach those really tricky places. For £10.99 I'd get one for your tool box. Ideal for looking down plug holes into bores to check for any scoring
