ohh sad to hear about this.. bhai Insurance nai karwai car ki 
Try Honda fort, i hope it will be available there.. hmm yeah wali bi kai na kai bik jai gi which will results in some cash recovery..
Another saving plan is, go for some Black Shades on rear lights, i hope you have seen some modified cars and they have like some black tape all over the lights and then cut them in round shapes etc.. hmmm these are some examples of what i am talking about..

it will not look good, but somehow you can save the 7800Rs expense.
Did you asked them that the whole light will be change or only the front glass mirror, try some local light/bumper repair shop and discuss with them.. may be they have some solution.. in this way you will have your original light with you.. Goodluck bro
