1. A hood bumper for a vehicle having a hood, the hood bumper comprising:
a housing having a wall, a base, an internal chamber, and an opening to the internal chamber, the wall having an interior surface and an exterior surface, wherein the interior surface defines the internal chamber;
a biasing mechanism operably connected to the housing;
a plunger operably connected to the biasing mechanism and configured to receive an exerted force from the hood, wherein the plunger is configured to move from an extended position to a compressed position into the internal chamber and compress the biasing mechanism when the force is greater than a first magnitude;
a bumper head operably connected to the housing, the plunger being configured to protrude through the bumper head in the extended position and being configured to fully move into the bumper head when the exerted force is greater than a second magnitude, wherein the bumper head is configured to receive the force from the hood when the exerted force is greater than the second force, and wherein the bumper is configured to be compressible when the exerted force is above the second magnitude; and
a support frame operably connecting the bumper head to the housing, wherein the support frame is collapsible from an uncollapsed position to a collapsed position when the force is greater than a third magnitude;
wherein the support frame is disposed radially inboard of the bumper head.
