You could have then installed in the outer and inner cowl? Just an idea.. rather like this electro illuminated panel

In fact you can now get Electro luminescent paint, so you could literally spray the cowlings and get the running engines cowls to light up!
Though it might not be as effective in daylight. I saw the stuff on Car SOS where they added a VW logo to a bonnet.
