It's reflectors so you shouldn't be putting LEDs in the headlights. Why do you need bright lights to see at night with window tint? I sure hope you aren't putting 5% tint on your front windshield.
Either way, if you need bright just go with a regular incandescant/filament bulb like what's in the car now. It'll have better light output than an LED would. Find one with brighter light output than the stock bulb and you're good to go.
