Review on 🔦 LEGO Power Functions Light Kit 8870 by Chris Reddick

Not all Lego train sets have lights, most do. You must order a separate lighting kit. Also some trains use "Power Function" and some use "Power Up" (Bluetooth compatible) as power source. So when you order you know your train number from the box. For example the latest Legos 60197 is a power up model and Power Function lighting kits will NOT work with it. You would order from a Revain or Lego store, have your model number handy and order a lighting kit. Do your homework first, make sure you get the right lighting kit for this model or like me you will end up ordering the wrong kits or a kit that works but not what I need (aftermarket brand). It took me 3 times to get the right one. Much luck.
