In this instructable, I'll show you how to convert an emergency light into a work light. I replace these LED emergency light units often at my work, so instead of throwing them away, I thought of an idea to convert them into a work light. These are really useful when working on or under your car or truck, or anywhere you need a light when working on something. Plus they are pretty bright & can be adjusted in any direction.

Step 2: Materials Needed

You will need: An ELM-2 LED emergency light unit, 9v transformer, Small switch, a Short piece of wire, 2 female spade connectors, 2 wire nuts, Electrical tape, Wire cutters, Utility knife, a Drill or Dremel tool.

Step 3: Gut The Unit & Cut/strip Wires

First you will need to remove the circuit board and old batteries from unit. (Be sure to recycle anything if possible.) Next, cut and strip the 2 blue & 2 yellow wires that go to the 2 LED lights. There should be 2 wires per side.

Step 4: Cut Hole For Switch

Next you will need to cut out a hole for the switch. The switch I'm using is a simple toggle switch that has 2 prongs on the bottom. Measure the switch and mark it on the unit with a pen or pencil. Cut out with a utility knife or better yet a Dremel tool. A Dremel will be a lot quicker. Install switch into hole.

Step 5: Prepare Transformer/attach Wires

Cut the plug end off of the transformer. Strip the 2 wires. Then attach one of the spade connectors onto a wire. Now attach it to the switch. Strip the short piece of wire on both ends. Attach a spade connector to one end. Then connect that spade to the switch. Connect the other end to the yellow wires going to both LED bulbs with a wire nut. Next connect the blue wires to the other transformer wire with a wire nut. Wrap up the wire nuts with electrical tape.
