1. A lighting system for a vehicle comprising:

  • a photoluminescent portion disposed on an inner surface of a closure of an engine compartment; and

    a light source located proximate the closure, the light source configured to emit an excitation emission at a first wavelength directed toward the photoluminescent portion, wherein the photoluminescent portion is configured to convert the first wavelength to at least a second wavelength longer than the first wavelength,a controller configured to selectively illuminate the light source, wherein the controller is configured to illuminate the light source to emit light at a first intensity or a second intensity, wherein the controller is configured to supply an increased voltage at a reduced duty cycle to produce the second intensity relative the first intensity.
