I have one neon light under the drivers footwell that plugs into the cig. lighter. I am going to get another one for the passenger side, Do I need to get a cig. light splitter for both plugs? I was thinking of using one plug for both by connecting the 2 light's wires together. Based on my small knowledge of electric circuits, the same voltage and hence current(same resistance in wires) through each should be the same since it is a parallel circuit. Would this work? Thanks
