Can you use the default lighting normally?
Be sure that in the Ref [name]: section is "test" without quotes. Also I strongly recommend to use the newest comment syntax: [<light_name> -<setting_name> <value> ...], by this you can freely override any default settings as you want for individual light. For example, if you just want to modify the light "test" radius and status, use [test -radius 120 -status off] instead of create a new custom light.
Also be sure that the image are properly located in /img/lights/, you can check this by double click on the Image [.png] setting and see if it show the image.
