Introduction: LED Helmet
This is a led helmet for under $10. In this project, 4 led strips have been mounted on the helmet in such a way that there is maximum visibility during the night time and even in foggy days and the person can be seen from all the sides.LED strips are connected in parallel due to the fact that in parallel combination there is minimum resistance and maximum current can flow through the led lights making them glow brighter. The LED strips used in this project are very thin and they do not contribute to the drag provided by the helmet to the rider thus not wasting energy and thin LED's are chosen so that in case of the wearer may suffer a fall and if head strikes against any hard surface, if the LED's were thick, it could cause damage to the neck of the wearer instead of rolling out smoothly of a fall as a typical helmet would do. An LED dimmer is also used for this project to avoid dazzling of other road users or observers.to make sure that the safety of the helmet is not compromised, it is made sure that no modifications are done inside the helmet or no parts are inserted in the helmet's shell and neither taken out.

Step 1: SUPPLIES REQUIRED
A motorcycle helmet, LED strips, 9v battery, an LED dimmer, connecting wires, 9v battery holder, on/off switch
TOOLS AND MISCELLANEOUS:
soldering iron, soldering lead, cleaning cloth, acetone(for cleaning and de-greasing), superglue, strong adhesive double-sided tape, black tape.
Step 2: Cleaning the Helmet
firstly, the helmet should be thoroughly cleaned with a cleaning cloth and acetone to make sure that there is no oil or grease on the surface of the helmet.once done, remove the sticky tape from the led strip and stick it to the surface of the helmet
Step 3: Soldering the LED Strips
Take the connecting wires and solder them to the LED strips. Take the wires and connect them in parallel that is all the positive ends together and negative ends together and solder them properly making sure that they do not come out.
Step 4: Connecting the Dimmer
once the LED's have been soldered connect them to the output part of LED dimmer and solder the wires to the parallel combination and wrap the black tape to make sure that the wires do not touch each other.
Step 5: Connecting the Battery and Switch
now finally, connect the switch and the battery to the dimmer which are further connected to the LED.
Step 6: Testing the LED Helmet
Finally, insert the 9v battery in the battery holder slot and connect the battery with the connector and....
VOILA!! the project is complete and working
