Yes, I will confirm that this mod is not entirely compatible with nvidia graphics cards. This mod was developed by a team that all used ATI/AMD graphics cards, and thus were not aware initially of the incompatibility with nvidia cards. However, as has been mentioned by volodya61, if you remove bec_submarine.dds from the textures folder, you should see the lights appear the same as in the stock game. The lights were edited to be more yellow in color as they are incandescent lights, where as the stock game has very white light bulbs....a minor difference I know, but realism is always striven for in this line of modding.
