I had installed 100/90 bulbs in my i10. While adding the relay and bulbs, the installer had cut the rear cap like something for wiring. Now this monsoons I am facing the issue of headlights fogging from inside and water droplets collecting.
The service center guy told me that since you have cut that plastic cap, water seeps in causing the fog.
Is there any solution like if I tape the cutout part. Many i10 users in this forum have upgraded their bulbs. Anybody else facing this problem?

Please help.

I didn't find the right solution from the Internet.
