Best Sunfilm & Headlight Setup for Hyundai i20 in Chennai?

Hey everyone,

Planning a few upgrades for my Hyundai i20 and wanted suggestions from people who’ve actually used these setups in Chennai conditions.

Sunfilm

Main priority is handling Chennai heat while still keeping good visibility, especially during night driving and rain.

Confused between:

3M CR70

Garware Icecool / Arctic Cool

Evo films

Humax

any other good options

Would like to know:

which one actually makes a noticeable difference in cabin heat

night visibility experience

durability/bubbling issues over time

legal shade recommendations

Headlight Upgrade

Stock headlights feel a bit weak on highways and during rain, so planning to upgrade them too.

Considering:

Osram LEDs

Lumax LEDs

any projector/fog lamp suggestions too

Also confused about colour temperature:

warm yellow

warm white

cool white

Which colour works best for:

rain visibility

highway driving

city driving without blinding others

Would really appreciate:

your current setup

beam performance and throw

trusted shops/installers in Chennai

approximate pricing

Thanks!
