Please check the weight of the lamp,and the device you have attached, whether the motor you have used can take the load, if yes use a plastic sheet to secure it in place by a bolt/ screw/s. This can be mass produced and will also be secure. If cost is not a constraint use aluminium plate, this could also be mass produced by die casting/ moulding and /or forging.

Thank you. Originally I used a sheet of galvanized iron, however, it is poorly attached to the engine - it was warped. So I just had a thin metal plate instead.

If I understand correctly, you are using a stepper motor to move the light, and you are looking for a more robust rotating mount which is simple and cheap.

First, I would reduce the length of the arms on the U bracket that the light is mounted on. Longer arms create more stress on the motor bearings.

Second, I would find a stepper motor with a longer shaft so that you can screw a collar onto it that will be attached to the U bracket. The collar would be attached to the shaft with a grub screw.

Third, make a bearing from a flat piece of nylon or teflon and a smooth flat steel plate that the bracket and collar will sit on. The bearing will go between the bracket and the top of the box. You may need to use a geared stepper motor to increase the torque.

Tony Kerr it is a good idea (the system) but it is also suitable for use in my next project. The new aircraft ‘Glaybox’. This new flying device two parts of the fuselage must rotate relative to each other (probably). And there is the problem of the reliability of the connection of the rotating parts in flight.
