Nesting Robins and garden fairy lights

I've just been putting up some solar fairly lights on a hedge / bush running down the side of our garage wall

In the last stages, I notice a Robin looking very attentively as to what I was up to and skitting in and out of said bush

Having now looked up Robin nesting behaviour, I'm assuming the Robin has or is building a nest in there

The lights in questions are pretty restrained (not bright and will be dimly on as a constant (rather than flashing disco lights)

Will the light disturb the Robins or potentially be an insect attracting 'feature' as the year unfolds? ..I'll take the lights down If they will be an issue
