Hey I'm new and just had this issue myself. I replaced mine at HUGE cost but kept the old one to fix. Your leak is probably goint to be in the same spot as mine (assuming your bulb seals etc are in place. The leak will most likely be along the top edge (where the two halves are glued together), and along the portion that is covered by the hood, not the fender. You can get a hobby syringe, fill with silicone, and jam it into every crack and crevice you can find along that edge. Should help to ensure no recurrence.
