The lamp you described is likely to be **Wing Scan Lights** or **Wing Inspection Lights**. Its main function is to help crews or ground staff check the condition of wings and engines at night or in low visibility conditions.

### Specific use:

1. **Check the surface of the wing**:

- It is used to check whether the front edge, rear edge, flaps and slats of the wing are frozen, damaged or other abnormalities.

- In cold weather conditions, freezing is an important safety hazard. This lamp can help confirm whether the wings are frozen.

Two. **Check the engine intake channel**:

- The light can illuminate the engine intake channel and help check for foreign matter or freezing.

3. **Auxiliary ground operation**:

- At night or in low visibility, this lamp can provide lighting for ground staff to facilitate the inspection or maintenance of wings and engines.

### Features:

- It is usually installed on the lower surface of the wing close to the fuselage, and the light direction is outward, covering the wing and engine area.

- The light intensity is high, which can provide sufficient lighting.
