The Olight rig is compatible with RN400, RN800 and RN1500 lamps. The handlebar adapter shown in the picture is a separate accessory.
The product is a replaceable spare part, a small plate that can be seen above the number 4 and can be attached to the RN lamp housings with two small screws. This allows the light to be attached to the steering wheel adapter.
Not compatible with Allty 2000. It is the same in terms of shape, but this part cannot be removed there.
