before i did the black housing i tinted mine with 20% tint and it was like that for a year with no problems
so i would suggest it

i can't find the pic of them off
if you tint it it will take like 5mins compaered to a long time to
take them apart and paint and glue back together

i just recently re-did my bumper lights because the light output was horrible
cause i took out the diffuser piece of plastic and painted the whole housing black
now i painted part of the inside neear the bulb silver and made a piece of plastic to diffuse the light
