Hufcor Bulb Seal Crimping

To keep the bulb seal from sliding up or down, you need to crimp the retainer. It is common to use a sharp tool like a screw driver tip, however, this might ruin the retainer for future bulb seal replacement. A blunt ended tool should be used like a punch. On future bulb seal replacement, the crimp can be pryed apart using a flat head screw driver.
