First remove the bumper and remove the projectors to check for any leakage to see if water got in there and burned out the bulbs.
If there is no leakage, drill as many holes in those as you can so yourself and no one else can use them. Then throw those pieces of shit away and get some real projectors that actually work........like TYC or go back to stock.
Those projectors you have right now are ugly, nasty and gay.
