A car lamp includes a holding member, and several loop-shaped lighting members; the holding member has several lamp holding holes, a holding recess around each of the lamp holding holes, and several light passages communicating with each of the holding recesses; light sources are secured right behind respective ones of the light passages; each of the loop-shaped lighting members has equidistantly spaced light-condensing bumps thereon, and is fitted on a respective one of the holding recesses on the holding member; thus, change of the light sources is allowed, and light with a closed loop-shape will show on each of the loop-shaped lighting members when the light sources are powered.
