That is exactly what I have done, the stress along the glass is what I concluded was the danger to the units.. What LED bulbs did you fit and where from??I changed my DRL's to led and became an expert at removing and replacing my light units. When I replaced them I used some rubber packing to make a sort of washer/packing piece before only lightly tightening up the three top screws. the bottom locator goes back easily with a bit of vaseline applied.
