Dorman's Headlight Bulb Retainer provides a longer-lasting and more affordable repair solution for Ram ProMaster vans. The socket features a patent-pending reinforced locking tab that solidly secures the bulb, simplifies future replacements, reduces maintenance costs, and helps ensure safer driving conditions. The retainer is designed to replace the OE headlight bulb pigtail locking tab, which the company says has insufficient holding power and causes the headlight bulb to loosen and disconnect. When the locking tab breaks, the hot halogen bulb has been known to fall out of the socket entirely, landing inside and melting the plastic headlight housing.
