This invention presents a method for overcoming limitation in brightness and heating effects for LED based Precision Approach Path Indicators and allowing both colors to be imaged in the far field with the proper abrupt transition between the red and white sectors. This method relies on the use of linear arrays of LED's and cylindrical optics.
