Saboor bhai i took the light off the car, pored some water, rinsed nicely and then put some shampoo in it with a little amount of water and again rinised it nicely, then washed it with lean water untill all the foam/shampoo was out
after that i placed the light on the ground so that water can be drained, after that used blower to drain the water whih was left in it.
then took two clothes and inserted into the light from the bulb area, placed the headlight in sunlight so that the water left in light will evaporate and will get absorbed in the clothes i inserted , at the end i applied silicon to all the seals so no water may get in next time
