Blacked out headlights?

Hello everyone... I think I saw something like this somewhere before, it allowed your headlights and tail lights to be entirely black during the day but when you turn the lights on it looked normal... or relatively normal... anyway could somebody dirrect me to where I could find something like this online. Thanks.

i've used a spray can product before that tints your tail lights. it can be hard to use and if not done right will look matt instead of glossy. i found out the hard way. wouldn't do it to my bike because i like to be seen. but thats my opinion. as for headlights, if you get a headlight protector and then tint that. it might be expensive to replace a headlight if you make a mistake. other considerations- is it legal? will it affect the plastic? will it burn due to the heat of the headlight not being allowed to dissipate

hope i've helped and good luck beast

if you want to do it , VHT makes a product called night shades
