THIS IS BRILLIANT, literally. It’s slim, mere millimetres thick, just over a foot long and looks like a ruler out of Star Trek – until you connect it to a battery when it lights up, well... brilliantly. Sealey’s Slimline 12 LED 12v inspection lamp ( LED042) is excellent for boating because it clips to the batteries for power and has a three-metre long cable so you can mount it in the engine hole (you’ll have to get some clips or Velcro) to provide general light, and then you can use it unclipped to poke around the mechanical bits and get into the tightest of spaces. Unlike a normal lamp it’s also resistant to oil, chemicals and water so it will last. List price is £ 54.95, but as we went to press it was on offer at £35.94.
