1. A lamp with light guide lens for lateral illumination, comprising: a body with a front end and a rear end, a direction extending from the front end to the rear end being defined as an axial direction, and a non-axial direction being defined as a lateral direction; a light emitting element disposed at the front end of the body; a light guide lens disposed at the front end of the body and abutting against the light emitting element, the light guide lens including a first end, a second end and a peripheral surface between the first and second ends, a concave reflection surface concave toward the second end being formed at the first end to reflect a light emitted from the light emitting element into the lateral direction, and the second end being formed with a recess for accommodation of the light emitting element, wherein the recess includes a bottom surface and an open end, and the bottom surface is an arc-shaped surface convex toward the open end; and a movable housing movably disposed at the front end of the body and including a front light-passing portion, a lateral light-passing portion and a reflection cup between the front and lateral light-passing portions, the reflection cup including a hole facing the light guide lens, when the movable housing moves until the light guide lens is located within the hole, the lateral light from the light guide lens will be reflected by the reflection cup and emitted out of the front light-passing portion, when the movable housing moves until the light guide lens is not within the hole, and the lateral light-passing portion extends out of the body, the lateral light from the light guide lens will be emitted out of the lateral light-passing portion.
