Got this wild idea about making a LED headlamp and i started off with a simple setup to check the effectiveness of white light from LEDs. This is my 1st step (or 0th step  ) towards the goal of making a full fleged LED headlamp. i ve started to study about various lenses, i guess i ll improvise the design(try to make round ones with hundreds of LEDs and get the light focussed with the help of projector lens) over the following steps.
Components:
30 5mm White LEDs
10 82ohm 1/4watt resistors
PCB (bread board type)
Araldite adhesive(epoxy)
Fevicol SH adhesive
Some pieces of wire.
Araldite applied and the LEDs arranged
30 LEDs were divided into groups of 3 with 1 resistor per group and soldered
After soldering, a thick coat of araldite was applied to make it waterproof and another coat of fevicol was applied.
Testing
Snaps taken from front of the scorp
The light inside the marked area is the light produced by the LEDs(no where near the power of headlamps, but still can be used as auxillary fog lamps with some improvisation).
And as i mentioned before, i bought some goodies(cheap blue neons and Philips rally 130/100 bulbs) this weekend. Quote:

i can give it a try but i dont know the exact size and design of the cabin light.
