STEP 1: Step 1. Material
Existing emergency light , I had is SUNCA rechargeable cfl light with 6 volt 4.5 ah smf battery. 2 x 6 Watt CFL
1.Power LED 1 Watt with heat sink - 5 Nos x 10 = 50 Rupees
2.Resistance 10 Ohm 5 watt or 4.7 ohm 5 watt for more brightness - 1 No. x 5 = 5 Rupees
total cost is Rs. 55 in India , around 1 $ in US

STEP 2: Step 2 - Circuit Diagram
Make the changes in wiring as shown in Circuit diagram. Radio, cassette player kept as it is, only CFL power is disconnected. and Bulb & 2 CFL has been removed.
STEP 3: Step 2 - Assembling
Solder LEDs carefully , LED are heat sensitive , connect wiring as shown in circuit diagram. Apply little glue to LED heat sink base to fix LEDs.
STEP 4: Step 4 - Finishing
After completing wiring check for dry solder loose contacts etc using multimeter . Then switch on Emergency light to test the LEDs are working fine, then close the acrylic cover . Now here it goes Live.

Wow, I had no idea you could make one of these yourself. You have some pretty easy-to-follow instructions on here too. I've been considering starting up a tow truck business. I would definitely need a lot of these lights for that. I could probably save a lot of money if I could make them or find them at a cheap dealer. The light you have on this post isn't exactly what I need, but there are some on this site that are similar to what I need: <a href='http://www.ledqusa.com' > http://www.ledqusa.com</a> Is it possible to make lights like this?
