ABSTRACT OF THE DISCLOSURE A lamp replacement tool which provides for positively captivating lamps for ease of removing or inserting lamps from or into the type of a lamp housing that forms part of a flush mounted push button switch used in aircraft cockpit control panels. The lamp is mounted behind a display legend formed on the face of the push button and for lamp replacement the push button portion of the switch unplugs from switch body and hinges down to expose the rear of the lamp. A friction fit maintains the lamp in the lamp housing. The lamp replacement tool includes upper and lower blades extending from a handle member in spaced apart parallel relationship. The lower blade is formed with a forked end portion having a u-shape for engaging with a flange formed on a base portion of the lamp and for embracing the base portion. The upper blade is formed with either a v-shaped portion or an aperture for engaging with a base contact protruding from one end of the lamp. The upper blade terminates in an angled lead-in. The lead-in provides a smooth surface for sliding over the base contact as the upper blade flexes over the base contact when the tool is pushed into engagement with the lamp. The lamp is locked or captivated between the upper and lower blades of the tool when the u-shaped end of the lower blade embraces the base portion and engages with the flange and the interior surfaces of the v-shape or aperture portion of the upper blade engage the periphery of the base contact.
