Lego lights

There are numerous models from various categories like Friends, City, Star Wars, Harry Potter, Technic and so on. Buying separate light kits for each will cost significantly and you might not even get kits for the sets you have.

DIY lights can be the one-stop solution to kill two birds with one stone. At the same time, youngsters who buy their models by saving their pocket-money or those who work shifts to earn money for buying the Lego sets they are so passionate about, can find a cost-effective solution to lighten up the Lego models.   

So, before you get started, make sure you have assembled the Lego set to know where to put LEDs and pass the connecting wires. It is easy and interesting to create your DIY LED lights and the 5mm LEDs are the most suitable options for this approach, although you can go with other pieces too.

The accessories you will need are soldering gun, hot glue gun, electrical connecting wire or sufficient measurements, batteries for the LEDs along with battery holders and a dremel or drill with 4.9mm or 5mm drill bit. Get a small file (something similar to that will do too) or small-sized grinding head (if dremel is used).

Make DIY LED Light Kit In Easy Steps

The first step in DIY light building is to arrange as many Lego pieces of different sizes and colors you require along with plenty of LEDs having different brightness levels and color variations(click to check the more detailed guide from INSTRUCTABLES)

  • Now, for the Lego lights¸ drill 2 holes into both marked ends 5mm from bottom of the brick and 4mm from each side of it. Drill 5mm holes on bottom of brick through tube-like structures.
  • LEDs need to get stuck atop another brick and so, you have to decrease the height of tube-like structure. Use file or grinders to cut the tube structures up to 5mm height and push the LED through the hole to check whether it is flush-mounted with the brick.
  • Long-headed +ve sides of all LEDs should face the same side i.e. holes on bricks. Bend leads of an LED out sideways so that +ve side is on the left and about 3-4mm of it is sticking out on either side.
  • Solder 2 short wire pieces 10mm onto its ends at 90-degree angle from leads. Pass the LED with leads from one end so that the leads poke out through holes made on the end of brick. Follow this for the next LED with +ve side on left.
  • Carefully so that the brick is not damaged, solder leads together and make sure there is proper spacing if you are soldering outside the brick. Test the connections afterwards.
  • For the DIY Lego LED lights, you need to connect several bricks in one circuit. Cut a little piece, strip its insulation off and fold the wires onto oval shape. Put two ovals on both sides of back-hole of brick and solder them respectively to their leads.   
  • Put glue between brushes and make sure they are not expanding too high. Use drill bit to make holes to attach wires from the next brick.
