Abstract: A mobile illuminating tool tray includes upper and lower compartments and wheels attached to the tray for mobility purposes. The lower compartment includes a lighting fixture and bulb used to illuminate the upper compartment and the underside of a vehicle while the vehicle is being repaired. A floor member separates the lower compartment from the upper compartment, which is used to support tools during the repair process. The floor member is translucent and/or transparent to allow the light to shine upwardly during use thereby illuminating the upper tray compartment, repair tools and the underside of the vehicle.
