Abstract A combination weatherproof and pressure relief cover for an automotive lighting fixture is herein described. The cover or boot, as it is called, covers the lamp receiving end of the fixture. An internal molded O-ring is formed on the inner surface of the boot which seats within a dovetail-shaped groove on the fixture canister, thereby locking the cover to the canister. Due to the resilient material of the cover, excessive pressures built up within the fixture can escape by way of the pliable locking Oring of the boot. When the internal pressure is relieved sufficiently, the locking O-ring reseats itself in the groove. This arrangement assures a weathertight seal and prevents contaminants such as dust and moisture from entering the fixture.
An automotive headlight comprising: a canister; a lens attached at one end of said canister; a removable pliable boot fitted about the other end of said canister; a reflector disposed within said canister, said reflector being directed toward said lens; a lamp holder disposed at said other end of said canister and within said boot, the edge of said other end of said canister being recessed to define one half of a dovetail slot, the other half of said slot being formed by bent edges of said lamp holder; a lamp disposed within said reflector; and a pair of power wires electrically associated with said lamp, extending through said boot.
